A monthly cap actually makes some sense. I'm strongly partial to the knowledge as a public good argument, and would see it paid out of some sort of a general fund somehow, though getting from here (piecemeal / advertising / gratis / occasional subscriptions) to there (centralised revenues collection, some sort of content rating / pricing differential, use-tracking for author/artist compensation) seems difficult.

Amazon are doing something vaguely interesting with an all-you-can-eat monthly subscription concept. I believe O'Reilly's Safari operates similarly.

My introductory paragraph was meant to convey that I thought I'd be suggesting something probably not entirely welcome as it goes rather against the concept I'd understood Brave was based about. It apparently did so poorly, and I may be wrong, I often am.

I'd commented in an earlier HN thread where Brave was announced, though suspect you hadn't seen that. I've written a bit on content syndication and issues of information goods and market economics (they play poorly) at https://dredmorbius.reddit.com/

I'm not active in the space though I've given it a lot of thought over the past few decades.
