Yeah, you can go with a Linux phone but forget about:
- controlling any IOT device
- using any smart watch/sport trakcer
- Android Auto or any remote car features
- mobile banking
- authenticating at work
- buying public transport tickets from your phone
- using apps for boarding pass when flying
- charging your car at most public chargers
- using any type of digital ID or documents
If you're already a luddite that's awesome, you're free to move to Linux phones. If you like modern tech and the convenience it gave us it will be really fucking sad to lose all of it because or corporate greed.
