AFAIK apps like Infinity are not paying anything because they're currently considered "accessibility tools", although I'm pretty sure they are still subject to a rate limit and a restriction on being able to view any posts labeled or mislabeled as NSFW.
As for the ones who aren't exempt, I guess they're reasonably comfortable with the position they're in, personally I can't say I'd be. One months notice to rugpull an entire API featureset? No thanks. Long prior notice, planned deprecation period are the industry standard, with extensions as necessary. Things work differently in FOSS, but Reddit is not a FOSS project.
I feel like Spez got upset Apollo was featured in the Apple ad and they weren't.
This made me literally laugh out loud, wow
