Migrating is such a good feeling. You don't have to do it all at once, either: I migrated to fastmail over the course of several years. Each time google did something that got my blood pressure up I went into my password manager and migrated another account. In aggregate it was a hassle, but these days I almost miss the feeling of being able to do something in response to stinky actions from google.
I recently migrated off of my legacy "Google Apps for Your Domain" (now Workspace) account to a mix of self hosting and a regular old vanilla gmail account.
It was a real eye opener to experience how challenging it was to move my data from one Google account to another. Takeout is nice in theory, but there is no equivalent "Takein" service that accepts the data form import to another Google account in the format produced by Takeout! I naively assumed "Export Google calendar from here, import same files to there" but nope, that did not work at all. Maps data was even worse.
I've migrated everything from Google except for Google Voice. I have yet to find an alternative that can match the feature set and ease of use, regardless of the cost.
Anticipation of stories like this are why I didn't rely much on Google 20 years ago.
Never used Gmail other than as a throwaway account.
Went many years before I had a Youtube account. Finally made one to upload some videos. I am normally not logged in.
(OK, OK - I was more concerned with them suddenly charging for a "free" service, as well as selling data to commercial enterprises than with them giving to the government).
(OK, OK - I do use Android).
I don't think fastmail is going to help you. They are subject to legal requirements too and probably American jurisdiction also despite what their particular position is. https://www.fastmail.com/blog/fastmails-servers-are-in-the-u.... People love to hate Google but they're just doing what any corporation subject to law is going to do.
