> Both can be bridged to Matrix, which can be accessed with any OS you like with FOSS software. Correct, and I do exactly this. But WhatsApp requires a mobile device. It can work without the device turned on, but after a few weeks it will stop working. So you still need to have a phone though you don't need to bring it with you. iMessage and SMS is totally not a thing at all here. But Telegram is (which doesn't require the mobile app luckily, in fact I really like Telegram despite the lack of end 2 end encryption in regular chats). They allow alternative clients, bots, and their paid plans are cheap enough and offer some features that are genuinely cool and useful. I use it most of the time with local people here instead of whatsapp, I only use that with the few people that don't have telegram. I'm just mentioning this because in the US telegram appears to have a bad rep somehow. But to me it's one of the services that's the least trying to enshittify. Even Signal I don't use because it's just not terribly useful the way they implemented it. > Almost nothing is truly mobile only. You can run Android applications on QubesOS in a pinch, but more generally I find most 2FA apps actually use TOTP or FIDO under the hood, and can be replaced with open alternatives with a bit of research. That won't work. My work requires MDM management of the mobile device for accessing work stuff. And the 2FA app is unfortunately not TOTP or FIDO. And I agree with you on the cash part yes.
