>Starting with google: AMP does not actually make loading any faster. Google just uses it's search monopoly to make it seem so.
This is a complete misunderstanding of how AMP works. Google isn't abusing a monopoly to make AMP-pages appear artificially faster; they actually are faster. That's because they're safe to preload by design, as lern_too_spel explained already.
The monopoly comment makes even less sense when you consider that other search engines do the same, and even host their own AMP caches.
