Other than the countless lawsuits and the joining-a-pseudoreligion-that-claims-to-cure-The-Gay and the weird sham marriages that don't display a mote of sexual chemistry and the greater-than-9000 rumours of bathhouse hook-ups and the fact that as a paid actor he can't fake chemistry with women on-screen EVEN THOUGH THAT IS HIS JOB and he accidentally creates chemistry with men on-screen EVEN THOUGH THAT IS THE OPPOSITE OF HIS JOB?
His particular kind of psycho and self-righteous prickness is of the type that is of a person desperately trying to hide SOMETHING. But the thing is, almost anything else in the world he could be trying to keep a secret about would not damage his marketability as a leading man in movies, what with celebrity culture as it is today, nearly anything else would be forgiven within three months, except that if he admitted he was gay, middle-aged ladies in Iowa would no longer go to movies where he pretended to like a lady. And he would make less money.
Nine times out of ten, that is someone trying to hide homosexuality in a field where open homosexuality is not accepted or at least was not accepted when they were coming up through the ranks of that career field. Christian church leader, conservative politician, leading-man-type actor, etc. While the community of male actors generally has a higher concentration of homosexuals than most others, Tommy came up in a time where if you were obvious about it, you were instantly typecast into small campy comedies or character roles or had to be the uncle on "Bewitched" or something.
There are probably hundreds of people making their money off of being in Tom Cruise's circle and they're all scared that if he comes out, he'll go from making 50 million dollars a year to "only" 5 million dollars a year, forcing him to only employ hangers-on in the dozens instead of the hundreds and so they talk him out of coming out in a manifestation of their own fear.
Dude's gay. Dude's REALLY REALLY gay. Nothing wrong with it other than how far he's gone to pretend he isn't, of course, but it is also arguable that it is REALLY REALLY WRONG how much he is pretending, in this day and age.
