>> Gosh, I'm pretty much as anti-copyright/pro-freedom of information as anyone you would ever meet.
You aren't even close. Stopping just short of copyright maximalism doesn't make you anti-copyright. It makes you slightly more reasonable, but you're still on the opposite side of this particular debate.
> But like, megaupload? Why should such a business model be allowed to exist? 100% parasitic.
What's so parasitic about a file hosting service? They get paid a premium right now because they're taking on a bunch of legal risk on behalf of their users. You can blame any surplus profits squarely on copyright law itself.
> Patronage? Who if not the people acquiring the material?
The patrons normally would be the ones acquiring the original copies, yes. At that point it would be up to them to decide what to do with those copies. Patrons would normally also receive credit for funding the production of the work. This model works well in situations where there is social capital (or simply a sense of self-worth) linked to being known as a "patron of the arts".
> Crowd funding? Won’t that be in competition with the pirated commodity?
You're thinking of pre-sales. Crowdfunding is more akin to patronage, just with a broader audience. Backers might get some perks, such as public credit or merchandise, but there is no guarantee of exclusivity. The resulting work may or may not be made available directly to the public, though the distributed nature of crowdfunding pretty much guarantees that at least one backer would "defect" and make their copy available shortly after the initial release.
> Sponsorship, like ads in the content?
Product placement is one form of sponsorship. It can be done well, or poorly. Quite a bit of quality content has been produced for free distribution through unobtrusive sponsorship arrangements. Sometimes content that people are interested in for its own sake also incidentally happens to benefit someone, so they're willing to pay for its production even without any direct promotion.
