You can pull in emails from your old gmail via imap into your new account. Within roughly 5 years from 2010 to 2015 I switched over from an iCloud account and gmail to a custom domain and server. In that time, almost all logins were transferred. 5 years is a long time, though.

When mighty G would ban your account (completely with Google services, Youtube and whatever) you would know.

Or just a plain 'Wrong password' except it's the right password, it's just Google thinks it's wrong, but you can't do anything with that address.

Funny, this last one just happened to me and I blamed myself. I made an account for my son, wrote down the username/password then didn't touch it for nearly a year. I got to log in and it keeps saying wrong password.

As someone who was in tbat situation: Gmail allows you to configure some account to have almost a full access to other Gmail account; do that for any important account you provision.

Why would you wish to stick with Google? They’re proving every e-mail you’ve ever sent or received for data.

They will only become worse and worse, the trust I had in them is long gone. Just avoid them and let them go out of business

Google is bad, but every other company and your ISP and your hardware manufacturer is also probing your emails.

It's a question of size. I use Fastmail, and even if they do that (and I hope they don't), it's a relatively small company, so the impact is also smaller.

How?

Both are asked by your various governments to spy on you. I am not privy to the most current technical details - if you go through old NSA presentations that Snowden revealed I am sure you'll get the general idea of how it works.

Because gmail stopped supporting user/pass auth and instead switched to a retardedly complicated Oauth nonsense.

But the situation at most email hosts is like this: they only support user/pass auth, no 2FA.
