The distinction between "art" and "pornography" is also somewhat artificial. It's hard to argue that [3] was not meant to be prurient when the model (underage, by today's standards) shortly thereafter became a mistress of the King of France, based on him having seen the painting. And some stuff that was painted might get you banned from OnlyFans even today, e.g. [4].
But the problem, it seems to me, is that the internet has turned into a place where (1) everything has to be "safe for children" and (2) said safety standards are defined (through US influence, I strongly suspect) to be highly permissive of violence, but super strict on nudity.

That is exactly the problem I have with it - weasel words and euphemisms; FF is scoring an own-goal here and eroding trust.
Why not just tell it like it is. "We need funding and are lining up deals with third parties to display their ads/messaging in the address bar search. We vet these third parties by holding them contractually to these standards [list standards to establish bar required for "trust"]."
It's only my opinion, but spelling it out clearly - the need for funding and how/why "trusted partners" get to display their stuff - would make me far more likely to allow these suggestions. (Oh, and as for "relevance", FF should explain how that's intended to work, ie what data are being used etc.)
This is exactly the point why I left Google Chrome back then and considered FF as a good alternative. I didn't trust Google anymore. But now I face the same problem again, because I don't want these "features and trusted partners". I also don't want to have to justify over and over again why I don't want them. I just want a well-functioning and secure browser that people can trust.
