The obvious end result of this lawsuit is that porn stars will not need to be tested which will lead to more HIV infections which will then lead to lawsuits against the studio for pairing them with an infected actor or actress which then destroy the industry.
Anyone with half a brain sees how this will all collapse on itself if the studios have no way of knowing other than by the actor's own words whether their performers are disease-free. No intelligent business person would risk capital in a business where they can't protect themself from lawsuits.
Nah. They will have to comply or else get lost. Something they can not do.
