I've paid for Onlyfans a couple of times. One girl was at uni with me and I was curious, didn't regret spending £5 for that. The other girl was someone who took candid shots of herseif at the same gym I go to! I was super curious who she was and spent £7 I think. It's not like I've spent £150 on a bait and switch or a bad punt, this is pret a manger money we're talking about. There are a couple of local escorts who also have OF accounts and they seem to be doing pretty well, I wouldn't blame them if they stopped escorting, I would.
If we were 18, female, a bit of a stunner and needed money, we'd jump at it with open arms. It doesn't take much for attractive girls to build up a following online, especially if they're not afraid to talk and vlog about themselves. You have to be a certifiable idiot to prefer sucking off old men for £80 a pop over making a quarter of a mil a year while traveling the world. I don't get why this is even a debate!! Being butt hurt about girls finding out a 'secret' way of not being prostitutes makes no sense at all.

Heck, you don't have to even have an Onlyfans page, you can just do sponsored content on Instagram, Snapchat, Tiktok and whatever else is out there.
Escorting and porn are seen more and more as a liability to your social media career. When you escort you only have an interaction and a monetary transaction with one person at any given time and it's very personal, most likely not very positive either. Social media and OF et al allow you to scale up financial transactions massively whilst keeping your distance. I don't know why anyone would choose the former.
I think what will happen is girls who can't function as adults, who are damaged in some way or psychologically impaired, will just carry on escorting because they don't possess the skillset and discipline to make social media and/or OF work for them.
The savvy ones will think it would be mad to do that sort of thing, especially when making money by being a social media personality is far easier and so much more lucrative.
