I've been told by a male friend who (quite successfully) uses several of these apps that even on that one that makes women initiate contact (is it Bumble?) the first message is just "hi" like 99% of the time. Meanwhile, that's a guaranteed way for a dude to get ghosted, on any platform where guys can initiate contact, as is responding with a reciprocal "hi" on that one. In either case the clear expectation is that the guy needs to present something interesting right out of the gate, very first message, and generally drive the discussion. (this guy attributes his success largely to his A+ chat game, so I'm inclined to believe his take on this)
There is also a power imbalance due to men being physical more powerful than women, which is a concern for most, if not all women.
* It's easier to find a partner when you already have one
* There are much higher standards in getting dates (akin to interviewing) than once in a relationship
* Theres a power imbalance due to cultural expectations that men are the pursuers
