Regarding pricing, Disney is a good example of a company who are highly restrictive of when and for how much their content is available. I wouldn't be surprised at all if this translates to higher piracy rates.
Ah, I see. Well, you're quite right about Disney, but they're actually rather exceptional. Most films that go out of print or become hard to find do so because they're just not very popular, and the apparently-tiny audience isn't enough to offset the costs of bringing it onto a new platform (which can run into tens of thousands - QA requirements are very specific and if you don't meet them exactly it costs the streaming operator nothing to refuse it).
And I meant MPAA members, not the industry org.
