For now I have gmail through thunderbird so I don't even need to look at google, which prevents me from accidentally creating an account by simply being logged into my email.
For me the scariest thing about Google is not their gross privacy violations or monopolistic ambitions. It's the fact that there's a pervasive public perception of them as a company composed of kindly nerds immune to commercial corruption, the whole "don't be evil" bullshit. People buy the character they created for themselves.
It's sad because I remember using Google in the early 00s, the company grew up with me. Now it's becoming a monster. They have their own operating system, their own phone, Analytics is everywhere. What's next, Google Broadband? God that would be terrifying, now that net neutrality is dead...
And have you heard Eric Shmidt's remarks on privacy? Very concerning.
There aren't any free private email services, you need actual computers storing data, not just algorithms, and it would be very expensive to buy data for anyone who asked without making money off them.
Self-hosting is really the only alternative.
