Reddit Blocks Old Design Login to Curb Scraping, Not Safety
So Reddit has decided that plain HTML is unsafe

Reddit now requires a login to access old.reddit.com, claiming it prevents abusive scraping and ensures safety. As a user who relies on the lean, plain HTML interface for genuine human content, I find this justification dubious. The new design is bloated with JavaScript and tracking, yet remains accessible without logging in. This move feels less like a security update and more like an attempt to protect their data goldmine from scrapers by forcing everyone onto a heavier, more controlled platform.
Let's dispel any notion that there are safety issues arising from a frontend, because that's pure PR crap.
