Seriously, Apple is "big tech," but they are the only one that appears to give a crap about privacy at all. And really, they put a lot of money and effort into it.
We need to give kudos when they are due.
Apple's Private Cloud Compute should have won some kind of Nobel Privacy Prize, which for some reason does not yet exist.
Apple is luxury big tech.
In this day and age, privacy is luxury, so that's what they sell.
I don't think there are any ethical motivations for them (or any other large corporation - none of them have morals so they cannot act morally). It's just that there's a market niche, so it will be filled by someone.
Only thing I wish they were 20 years sooner.
The person you're replying to is saying "Sites I use block all VPNs besides Apple's subscription service VPN" - I'm not sure they're not blocking it just because they fervently believe in Apple's privacy commitments and engineering :)
Only pointing this out because I love Apple's privacy story and don't want your reply to be misconstrued as sarcasm, and thus the reason why it enjoys a singular exemption is because its ineffective.
They still don't let me install uBlock origin + noscript. Whitelisting per-domain and per-site what can run Javascript does more for my privacy than anything else, and I can do that with firefox on linux and android, but on iOS I'm not allowed to install firefox.
There's obviously no real technical limitation since if you live in the EU you can sideload an alternative browser in theory (though apple has made it unrealistic in practice since they're ignoring the spirit of the law and instead doing their darndest to resist giving users even a whit of freedom).
