That’s a sad jump. I’d say support/embrace Linux mobile, but we know the app makers won’t support it (and shitty apps like Signal require a primary device running one of the mobile duopoly OSs) & we we know Google with its Web Integrity wants to lock down our web browsing sanctuary that runs on any platform. Yeah, we might be forced into it… or be prepared to go low-tech like going to the bank & calling.
For me this will be really bad if I’m traveling abroad since the website requires 2FA & SMS is the only option which will be roaming & even the annual number swap I do when I get a new SIM requires paperwork & waiting a week for processing. But maybe owning a phone is more of a burden due to lack of device control & privacy concerns.
