I pay for G Suite, it works well. If I have to migrate, I will, but it'd be very upsetting.

Music-wise, I have completely transitioned to Alexa and Amazon Music. The interface is worse, but they seem to be more stable.

I just wish I could upload my own music and have Alexa connect to Bandcamp.

Yeah but Gmail is one of the easiest things to leave (if you have your own domain). There are high-quality alternatives and moving is a half hour of work.

Leaving YouTube is nigh impossible.
