Isn't AMP available as an open-source library? I don't see the lock-in. Besides, Google has announced that search rankings will be affected by speed, not by what library you use. So, if your site is already optimal (doesn't benefit from AMP) or you want to use some competing project that also does a great job, you won't be penalised. I don't see the walled garden argument here.
