I think it’s a bit of a double entendre, because it’s also referencing this specific part of the report:

As the stock of “femboys” rose, the fate of porn featuring “straight” guy porn has fallen. Searches for “straight” on PornhubGay tumbled nine spots to 19th place, just above “cruising” and two spots below “cute femboy.” (Notably, “straight guys first time” is still in the 6th spot, though it was knocked out of the top five.)

So “straight” guys are “out” as a gay porn category and femboys are “in”.
