There's some atom of truth to what you are both saying as there are evidences pointing to both but there are no statistical findings to prove either one party wrong or right,just experiences to affirm your side
Gay porn viewers are not a monolith,they have different requirements that appeal to their fantasies, that being said,I remember an interview Colton Ford did back then when he was promoting his music and I'm going to use that to address this discourse, he said he was told by gay porn producers to market himself as g4p or straight as that was selling back then than an actual gay man doing gay porn,he refused and stuck to his guns and he became the pornstar he is despite the pressure of trying to find success in the industry and not conforming to what viewers wanted him to be but there was something he said in the interview that really touched me about the appeal of straight men doing gay porn and why queer men find it hotter than actual gay men in gay porn back then....."internalized homophobia",this had eaten deep in queer men back then and it's still eating deep in queer men now,we've all experienced it,hell I myself is still seeking therapy to shut it down,some of us view straight men as the ideal man and gay men as lesser than them hence the fantasy that they are real men, it's everywhere ,they are desired and wanted because they bring that sense of masculinity queer men crave and the thought of these men being "converted" shivers their spine, it's no secret this was the niche then and gay porn studios wanted in on it but as time went by,gay men began to love themselves more and that niche started to die out, it's been dying out now in modern times as straight pornstars and even mere content creators of this generation are marketing themselves as gay or pan/bi just to get that pink money,I mean it's even evident on this thread,I can't even count how many posts that have been shared on this thread of people accusing an openly gay pornstar of being straight or bi because they fucked a woman or fucked a transman,they have to walk on low waters now not to ruin their careers,I rarely see this fans accusing g4p like Bo Sinn or Delgaty of secretly being gay. Also the most followed male pornstars on Twitter,gay or straight was Rhyheim Shabazz ,an out gay man not even a straight man as popular as Johnny sins(that might change if he went g4p) could achieve that feat,he had a million followers and would've been on his way to 2 mil if his account wasn't suspended,even currently he almost has the same amount of followers as sins despite starting his account all over again, he's great at his job but I personally don't think he would've achieved that feat today if he was straight maybe back in the day but not today and he's not just the only one, it's a fact that gay pornstars are much more followed than g4p and it's not just about the performance of the performer, anyone can fake that, it's the fantasy that he's really into dick than acting like he is not to mention the backlash some of them receive because of the history their predecessors built as highlighted by

TL;DR the g4p niche is literally dying out
