Certainly true, though presumably Kanopy in turn has to pay license holders for the films they offer? If it turned out they were gouging libraries I'd be incensed, but I would tend to think it's at least as likely the the studios and distribution companies are charging Kanopy a lot.
I'm just saying "generous support" makes sense as a word when it's NPR talking about donors, but is a weird word to describe the payments of your customers for a commercial service. Which makes me think they're trying to sound like they're NPR or something, when they are a commercial service. Universities and libraries don't pay for kanopy out of "generosity" or to "support" it -- it's a commercial service they subscribe to!
I have no idea what profit margin Kanopy makes, which is I guess how we'd determine if it was "gouging"? I don't know from "gouging".
