A lot of people have very closed-minded and frankly outdated views on porn.
Common take: there is no real pleasure on camera, the creators only give a performance, they numb themselves so they don't feel a thing, their acts and positions are all uncomfortable, they are probably addicted to drugs and are coerced into it.
A lot of the language in these discussions suggests that the people making these arguments only know of "classic" studio porn. Long, drawn out scenes with wild angles, enormous dicks only, very rough sex only, guranateed deepthroating, actors taking drugs to keep them going, the males get shit injected into their penises...
The thing is that the porn landscape has changed a LOT over the past decade or so, there is now factually far more independent content on the internet than studio porn. There is. I do not know how we could make sweeping generalisations about independent porn. How would we even begin to know if a scene shot at someone's home includes the kind of prep-work, drugging, and behind the scenes abuse as stereotypical scummy porn agencies (which do exist and used to be far more prevalent) do. Why do we think that this culture is an automatically self-generating given whenever sex is recorded? Does an angry misogynistic porn producer jump out the wardrobe when a woman decides to do solo content alone? And what, all women are incapable of actually orgasming even alone with a vibrator as soon as she records herself? Women are a monolith like that, are they?
I think this is a stubborn refusal to consider other ways of being, simple as that. For women who vehemently believe it's all 100% "fake", it may even be a defense mechanism probably mixed with a disdain for male sexuality. They simply have to believe it cannot be enjoyed, the thought is too subjectively uncomfortable, and it validates seeing any man who enjoys it and has a more nuanced view on it as a loser, an enemy, even. It's misandry at this point.
There ARE podcasts/blogs/videos/posts where sex workers talk about doing porn/erotic content in a different tone. It is a world that exists. In my opinion, the vibes of these people are not all that unlike from folks who like swinger clubs, sex parties, BDSM events with performances on-stage literally watched by people live. (and somehow kink culture is "live and let live" category...). Some people even enjoy showing themselves off or feeling hot. It's a thing. It is.
