Oh come off of it. That's some serious bullshit conspiracy nonsense you're peddling there.
A flag set on your local machine that blocks children from accessing porn, if their parents choose to set the flag correctly on their child's account, is not some big-tech privacy invasion. It's just basic good sense. I'm shocked that people would actually be opposed to it.
Opposing it has no practical effect other than helping strengthen big tech's argument that the onus shouldn't be on them to ensure their platforms are safe to use. That people should have to upload their ID to sketchy third-parties to verify their age before making an account on every website, because that's the only way we could possible know that children aren't accessing dangerous content!
If you're going to disagree with me, fine. But at least actually live in the real world rather than throwing out nonsense conspiracies. And respond to the proposal that's actually on the table. To the single user-configurable field that this guy was trying to put into Linux. Or to the ideas I raised in my comment. Not to some fantasy straw-man you've concocted, or to the big-tech nightmare that I've already explained I disagree with.
