This is the equivalent of a "Do you guys not have phones??"[1] but on a way larger scale.
At least where i live i am able to use the bare minimum of phones, even working with tech. The friction is increasing though, which worries me a lot, and day after day there is a new attempt to shove it down your throat if you want to be considered a member of society. Seeing that a lot of countries (including mine) are pushing for age verification, and the whole thing about Android blocking 'sideload', by the end of 2026 you won't be considered a human being without a government certified smartphone.

There's a line item which basically said "mobile web" and they wanted it gone to save some number of dollars per year.
It's all about better tracking. I'm not quite sure what additional info they get exactly, but tons and tons of mobile websites (that work and don't get deleted) are close to unusable due to a barrage of popups telling you to use the app (e.g. Reddit and other socials).
Also there is no indication they will stop the mobile web version. Already today the mobile web version is there but it explicitly refuses to show the boarding pass QR code: https://i.redd.it/lj3wdnfp9mq91.jpg
probably more guaranteed location tracking - hey this guy is buying tickets from the expensive part of town on the newest model iPhone! Chance we can jack up the price, 99% good!
