> Uhm, yeah, no. Less bloated JS usually means less concerns but privacy violations and tracking of visitors can very much happen on AMP. Some of that risk isn't removed, just shifted.

Um, yeah, yes. The whole point of AMP (and competing proprietary formats like FBIA and ANF) is that the preloading happens from a cache owned by the link aggregator, so the publisher doesn't get your details just because its page was prerendered in the background. The link aggregator obviously already knows that you're browsing over the article link, so there is zero privacy loss.
