I dislike AMP because it's Google trying to own parts of the web that should not be ownable. Every non-Google service I log into that allows external auth supports at least Facebook and plain old e-mail in addition to Google. Maybe your experience is different, but I use a lot of very mainstream services both free and paid. I know people who don't have Google accounts. I only use Gmail as a throwaway address for when I expect spam (e.g. signing up for dodgy-looking web sites). I happily admit I'm a huge fan of Google Maps and would not at all mind paying for it, and I actually do pay for YouTube, but everything else from Google has pretty good alternatives as far as I can see. (And even Maps has acceptable alternatives, it's just that much better.) AMP is like putting all the non-Gmail mail you receive on your Gmail account into a separate folder, and only including Gmail senders in your Inbox.
