Not so fast...
Much of the free porn you speak of that is damaging to the adult biz, such as entire downloads of complete DVDs/sites/scenes, is based upon content/copyright theft.
Such behavior should not be applauded, since it will result in more and more people that create the content to be forced out of business, and less work for the remaining performers. We're already seeing this...
The law will eventually catch up with the technology, and many of these thieves will find themselves facing huge fines that put them out of business, and lengthy jail sentences (amen to that).
Also, do not be so quick to laud the practices of some of the non-content producing companies that are profiting by advertising on the web sites operated by thieves.
What many of these companies are engaged in is a form of racketeering, where they profit from advertising on sites, while aiding and abetting the content thieves (since in many if not most instances, the advertisers are the primary/sole source of income for the thieves).
Let's also not forget that many of the pill/drug sites are operating illegally, and many of the dating sites are out and out shams, that swindle people left and right, with false profiles, and upsells to other programs (such as cam shows) that they also operate.
The thieves and scammers are having their day, but their days are numbered.
Eventually, if they keep at it, they will end up out of business and/or in jail.
