> Every respectable service allows you to create accounts using your email address, so please use that method to create your accounts.
Although using e-mail sign-up actually provides a number of privacy-related benefits over using the Google account way, it still doesn't solve the main problem - because the e-mail usually is GMail anyway (and when it's not - you can get blocked by Microsoft, Yahoo or anything else too, and you can also loose your own domain).
"Every respectable service" should let and recommend (but not require) you set a secondary e-mail and/or another way to contact you but they usually don't.
