Earlier quoted context omitted.
AMP can be preloaded because it's designed to be preloaded. Regular HTML pages have side effects that can't be accounted for. lern_too_spel is right. That is literally what AMP was built for. Let's watch as HN downvotes the correction while upvoting the misinformation in the top-comment. edit: Downvote and flag. Very disappointing.
This correction does little to refute the original point so...
>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.
