@amolith@masto.nixnet.xyz not to mention most people don't use a password manager and e-mail is essentially the key to all your online services. Imagine telling a non-techie he has to migrate his hundreds of accounts because Gmail is somehow bad. It's an insane amount of effort for something that seems not that important.
I'm doing my part offering free e-mail service at my expense, and so are you. That's a good start.
