Knockoff: A Free Browser Extension to Filter Fake Brands on Amazon
Amazon Without the Knockoffs

I built Knockoff, a free, privacy-first browser extension that filters out trademark-squatting pseudo-brands like SZHLUX and HORUSDY from your Amazon search results. By running entirely locally in your browser with no accounts or tracking, it highlights established brands like Casper and Carhartt while dimming or hiding suspicious listings. You can customize the strictness, hide sponsored ads, and contribute to a community-maintained list of real brands to keep your shopping experience clean.
The junk-brand arms race is only winnable together.

This says it's using AmazonBrandFilter's list of brands. Why would we use/support this chrome extension instead of the upstream one [1] which is actually doing the important maintanance task?
"Knockoff" seems to be literally describing itself.

Cuts two ways. Why should I pay $200 for a BigBrand dog bed if this knockoff site shows SHRDLU has the same thing for $40? We all know that BigBrand gets it from the same supplier.
The real knockoff problem I see is that you buy what you think is BigBrand and get shipped Knockoff because someone is mingling inventory.

I should check my purchase history, but I probably use Amazon more for buying stuff that they would classify as a "Knockoff", but isn't (i.e. there is no established brand they are knocking off). Because for legitimate brands, I try to simply buy elsewhere.
This is an example: https://www.amazon.com/MiiKARE-Universal-Rotating-Adjustable...
You'll find lots of different manufacturers selling this on Amazon, but there is no well known brand that makes these.

I worked for a hardware startup ten years ago now, and a big problem that was rampant at the time (and seemingly has only gotten worse) is that basically the Contract Manufacturers (CMs) in China take the BOMs and plans they’re given, and since they already have the molds, the same product will mysteriously be produced with a knock-off name, within weeks of your product being produced in china. At the time (and still) I didn’t know enough about whether the CMs are doing it themselves or they’re selling the information to a company to produce, or what, but if you want to manufacture something in China, you’re begging for it to be copied immediately.
While I have my own disdain for the current length of copyright law, it’d be great if China at least had some variety of it. This sort of crap may be an eyesore for the big companies, but its a death-knell for small startups, and Amazon is enabling it.

I own a dozen Amazon brands that are probably largely of the kind that OP would want this to get rid of (sourced from China, not name brands by any stretch, only sell on Amazon). For the most part I would say this extension is not a great idea (obviously very biased!), since I purchase brands that have high quality products that typically have pretty poor branding/online presence that I can improve. My stuff is very frequently of the same quality (and sometimes from the same factories) as much pricier stuff but at a lower cost. To some of those suggesting you can get this stuff on Aliexpress, in some cases that is true, though of course the big benefit of buying from Amazon is that there's no risk to buying no-name stuff because if it's junk you can return it.
In any case, I gave this a try to see which of my brands it would filter out. It's weirdly inconsistent.
One of my brands was filtered out because there's no brand name at the beginning of the listing. That's just an outright bad rule, because Amazon generally decides whether or not the brand name appears first. This brand is trademarked and has Brand Registry, so it qualifies for that treatment, just not getting it right now. Also, a number of other brands without brand names did not get the same treatment (and these are very much the type of products this is designed to filter out).
On another one, it misunderstood the product model, which is at the beginning of the product name, as the brand and hid it based on that. […]

Even better, buy direct from the manufacturer instead of Amazon. I've found most of the time you get the same price and free shipping without giving Jeff Bezos a dime.

I'm confused.
Counterfeit goods are clearly bad and a problem, but knockoffs that aren't counterfeit seem to be a good thing from an economics perspective, right?
A knockoff that isn't counterfeit isn't deceiving customers -- it is just competing and competition drives benefits to consumers.
There are many knockoff goods that reach comparable quality as the original, luxury good. We shouldn't support the idea of brands for their own sake. Today, many luxury brands are actually degrading in quality as the only thing customers are buying them for is the status signal more than the actual quality.
What is critical is a customer is informed about the trade offs between the goods to make an informed decision.
When I recently was buying camera gear, I bought some of the peak design bags and accessories (which are amazing). I then also bought some knockoff gear that is compatible with their system.
Real:https://www.amazon.com/dp/B07F94FQRB $29.95
Knockoff: https://www.amazon.com/dp/B0FYCB594Y $5.01
I knew what I was buying in both cases. I wouldn't trust the knockoff clips to hold my $3K Canon, but I am ok with the knockoff clips to hold an old, light film camera I also brought on the trip. I made an informed decision and my choice also helped contribute to competition between vendors, which is good for the market as a whole and consumers broadly.
If everyone used these chrome extensions, economic theory predicts that prices would rise for consumers and quality of the original brand […]

I'd rather buy a cheap knockoff than pay top dollar for an equally bad branded product. Most "consumer-grade" stuff out there these days is garbage regardless of price or brand. Examples: mattresses, home appliances, furniture, audio devices, routers. If you need something durable or dependable, you need to buy enterprise-grade stuff or make your own.
