Fucking to get your first acting role with lots of exposure is unfortunate but it's easy to see why most people would do it. Posters freaking out about it probably can't understand much about the real world with how they're sperging out over every casting choice in what is ultimately a family movie.
Ironically, that makes them oblivious to the fact that it's probably harder to use sex as blackmail if you're a guy since historically, it wasn't easy to be a not-totally-heterosexual actor. Imagine 20 years ago when Brad Pitt was starting out in the soap opera world, if he started mentioning all the dicks he had to suck he probably would have never gotten a career.
