This isn't true. You're basing this on the idea that their entire audience is people like you. J&J's bread and butter is still FFMs, and they sell. There is probably even a segment of their audience that is annoyed that they're not performing exclusively with women.
Delaying the release of the Girth scene is just a retarded business decision and is not going to result in any increase in sales. They think by holding off for a long time, they're building anticipation and more people will buy it (maybe this was a viable strategy in the 90s & 2000s when there were less options), but what will actually happen in 2026 is some % will check out and move on to other content creators. They are among the most popular creators out there, and they have a loyal customer base, so they're not going to go broke any time soon, but they're failing to capitalize on momentum when lots of new eyes are on them. They're also arbitrarily punishing the small minority of people who pay for porn and just annoying everyone who watches them for no good reason like with all the other needlessly slow releases.
