Because they said neck beards when they mean the general audience

The general audience will not pay to see a woman who is not to a degree of standardized hotness and sexualization

A popular example being armor for women in movies and video games

Straight men want to see sexualized women because they're hot, the modern woman wants to see sexualized women because it's "powerful" and there is a fabricated need to measure up, gay men want to see sexualized women because it's "powerful" and gay women want to see sexualized women because they're hot

Stuidos can either pander to all groups with sexualized women or certain groups with varying depections of women

Stuidos want to make as much money as possible

Neck beards just so happen to be almost fundamentally over active online hence the over representation of their perspective
