I don't disagree with you that a majority of women do not want unsolicited nudes. But there's not a consensus or black and white line between messages that are wanted or unwanted. Not all women are puritans, yet big tech censorship tends to push all interactions toward a puritanical moral ideal.
Personally, I'm interested in dating people who are sex positive, kink friendly, polyamorous and open minded. While I absolutely do not send unsolicited nudes or lead with crude messages, it can be hard to find people with a similar mindset when dating apps insert their morals between me and my potential dates.
I'm advocating for sensible filters and feedback, rather than moralistic censorship. Even if a majority of people agree with the morals. The only morals that dating apps ought to be concerned with are that the interacting parties are all consenting adults.
