I had my Gmail for almost 20 years and made the transition. It's annoying and time consuming but I think well worth it. I bought a domain and host it on iCloud. It's like $3/month for 6 email addresses (you can use it with the family). That includes a little cloud data and other services like hidden email addresses. DNS is handled by Cloudflare for free. Then start moving each service/login to the new email address. Every time you log into something, change the email address. I took the opportunity to update passwords and passkeys too, using Vaultwarden. I was lazy and had used similar passwords for a lot of services. Passwords are all long and unique now.

Now, even if Apple bans me, I can move my host within minutes. I never lose access to my email domain. It's much more professional and I can do catch-all. E.g. netflix@[domain.com]. This way I can see who sells my email address to spammers and block it.
