Loder is essentially proposing for ALL browsers to spam all websites that spy on users (essentially ALL of them) with automatically generated identity data and social media posts. That's a lot of spam.
Will it work? “If we can tar-pit spammers, we can tar-pit Facebook and Google from the browser.” NO. In this case, spam filters are THEIR friend, not ours. And if that's not sufficient, they'll simply ramp up email/phone verification or force users to sign up using their spyware phone apps instead of browsers.
Besides, Google's browser is by far the most popular. Good luck convincing Google to tar-pit Google.
WWW, Android, iOS, Windows - privacy-wise they're all broken beyond repair.
Decentralized, encrypted, anonymous, metadataless - that's the only way to roll.
