There's enough animosity out there to spread around between AMP and other centralizing forces. Calling one out doesn't implicitly give the others a pass.

Facebook (especially Instant Articles and video rehosting[0]) is awful for very similar reasons.

What's pernicious about AMP & co. is seizure of control and immense abuse potential that comes with preventing visitors from hitting content creators' domains.
