I'm thinking of Microsoft Accounts on PCs and how you need to know how to jump through hoops to avoid them at OOBE. And about how this is about AppleIDs and losing them - it's my understanding that Apple is less aggressive about AppleIDs than Microsoft is about Microsoft accounts, but also, TFA. Google has similar levels of fuckery especially if you're on Chromebooks but Google's sin is nonexistent customer support. I wouldn't want my most important email address to be tied to any of these three, although I speak as a gmail-using hypocrite who plans to change that soon.
The thing that really bugs me about Google is you can make an account tied to an unrelated domain, but then they don't let you use that for a lot of things, so you're forced into a gmail account.
