I know losing a YouTube channel is horrible, especially after you dedicated so much time, effort and money - and for some people it may be a source of income as well. It is totally unfair. But my nightmare in here is that you lose access to your whole Google account and that would devastate me. Not only email access (and thus, access to every service I use because I have my Google account linked to it), but also Goog…
So I would only really need to switch
1) my mail provider to something else, which is easier today now that I rely on "messengers" more than mail, so not many people that I need to inform. Just subscriptions and account details that I can update one at a time.
2) cloud storage to something else, and there are oceans of alternatives there, many very capable.
