It isn't, there's just a lot people out there who don't like women, don't like women with power, don't like women with power over men, don't like women using their sexuality to get power/money, and really don't like women using their sexuality to get power/money from men. So they invent a lot of reasons that porn is bad and unethical, the latest one is using the phrase "parasocial" to imply that any man who pays a woman online for sexual content is being exploited or manipulated in some way, as if every man has a gambling addict between his legs that cannot be trusted. It's ridiculous and motivated entirely by sexism masquerading as puritanicalism.
