This is what I don't understand about their API charges: Apollo (and other 3rd party clients) make API calls on behalf of a Reddit user. If I (as a Reddit user) don't pay money to use Reddit directly, why would Apollo have to pay to have me use Reddit through itself? It can't be a load issue, since presumably going forward I'd be making the same calls, just through Reddit's own app instead. Or if the load is reduced, then that means I'm using Reddit less, which doesn't seem like it's one of Reddit's goals here. Basically, why is Apollo paying Reddit for my Reddit usage, when I don't even pay Reddit for my Reddit usage?
