of course, you're right. On a higher level than me, because "what our lawyers tell us" IS in the end part of a strategy to squeeze as much money out of the thing as they can as well, by avoiding these troubles. But of course, beyond that, also by being able to charge more the way they do it, certainly. Still, in both cases (or both parts of the one case), it's not a "how the tech works" problem either way.
