The email search is completely useless. I don't understand how it can possibly be so difficult to do a substring search on a corpus and rank them in some kind of sane way. Searching for old emails based on content is an exercise in futility. After a few years of using an email service, search becomes really important.
It is exceedingly difficult to pull data out. You need dev ops skills to do it.
They charge for users that are disabled, and you can only stop paying for them if all of the associated data is deleted.
So they effectively hold your data hostage (yes, you can get it out but it time-consuming and requires technical skills).
I finally bit the bullet and paid a dev ops person (and gave him access to all my data) and switched to fastmail (at least it's not google) a few months ago. It's been an incredible relief.
