I don't trust reddit reporting that value accurately. Not saying it is a huge percentage, but they likely doing some things to minimize the numerator and maximize the denominator.

But yeah, definitely about control. They could have monetized users on third party apps with more reasonable API pricing. People would probably have barely noticed and that'd be new revenue for reddit that didn't exist before.

"Semper fi" maybe?

Yeah, but olive oil is also a mild laxative.
