This is one of the reasons why I ditched google, especially gmail a few years ago.

Yandex, pretty decent email web interface, and I can have my own @domain.com emails for free, if I ever need to move away from Yandex I can do so without telling everybody I "changed my email".

But I doubt Yandex will ever "inspire" me to move away form them, I think they dont even think of me at all, unlike Googles algorithms.
