I doubt iOS has a large market share in Iran.

Also, for something like this you don't want a platform that requires you to essentially use the App Store and nothing else.

iOS is around 10%, Android around 90%. (https://gs.statcounter.com/os-market-share/mobile/iran/%20)

   Briar is available on Google Play for devices running Android.

What situation do you mean?

The one you just summarized perfectly.

10% of devices or less.

Unfortunately, due to safety reasons Apple cannot allow you to leave the walled garden, it is only in your own best interest. All communication services on our iOS devices require at least one US-based NSA-integrated middleman. /s

Don’t forget the horror stories of people relying on iCloud to have all their personal life there only to get locked out for silly reasons.

Google is no better here, I would say they are even worse since they are scanning your files actively. Remember story of Father who was asked by doctor to send his baby son private parts photos due to covid and Google not only locked him out but also notified Police. Even after getting statement from Law Enforcement there was no crime they didn't restore his access. Guy lost 20 years of live history due to algorithm.

I feel the narrative on these kind of issues should be updated. We've been using their framing of "algorithms" but it is taking away all responsibility from the US tech workers who are actually designing and running Google.

The guy lost 20 years of life history due to US tech workers at Google wrongfully blocking his account and then ignoring his pleads for reactivation.

When US tech workers can show up to take cash and bonus payments from Google, they can also show up to take responsibility for Google's impact.

Seriously though, given all the NSA has done: Could the NSA launch a "beach head" inside Apple?
