Signal has clients for Windows, Mac, and GNU/Linux.

I have CalyxOS installed on an old Pixel 2 for "mobile app required" stuff. Signal can verify your account via a voice call to a landline phone number, and I have a cheap VoIP number that worked fine for that.

But the general point is taken. For example my HOA requires payment via Zelle, and my bank requires that I use their mobile app to make Zelle payments. I can still run their app on CalyxOS just fine via microG, but I feel like microG is something Google would find a way to shut down if it were to hit some critical mass of adoption.
