Spectrism

So you can't even argue your own point. Why make such a claim then? And even your point about it "not being 13" is debatable. I hope you are at least aware of Romeo and Juliet laws? Works just fine for most of Europe and Central/South America, where it's usually 14 to 15.

Why the hell is 17 "WAY" too young? What would be your ideal age of consent? 30?

This seems like a confirmation popup, according to the reduced brightness. While the cancel button is still visible, you won't be able to tap it and even if you could, it won't work because the account actually got deleted after selecting "Delete Account". And of course also because you're going to be logged out, as the message says. I have never used Uber, let alone deleted an account there, so I may be wrong, but I'm fairly certain that the account actually got deleted at that point, if my assumptions are correct.

Dark Reader can do this, though it requires a little bit of tinkering. First you need to tick "Enable on restricted pages" in the Advanced section of Dark Readers settings (in the old design the settings can be found under "More > All Settings"). Then in about:config, all entries in extensions.webextensions.restrictedDomains need to be removed and privacy.resistFingerprinting.block_mozAddonManager needs to be set to "true". If some of this doesn't work, there's also a GitHub Discussion with different solutions, but what I wrote here should do the trick.

Because it's proprietary garbage. If there are FOSS alternatives, I'm most definitely going to use them instead of proprietary software, let alone proprietary software by companies like Meta. And since there are plenty of those alternatives: No WhatsApp for me.
