So, "moderator bots and other tooling using our Data API" and concerns around that "[falling] into the free API tier" is definitely not the only issue cited in the link I provided.

Edit: Not only that, shifting mod tools to the free tier doesn't magically solve the fiscal issue third-party apps have and will still result in them shutting down. A huge part of the reason mods use those third-party apps is because Reddit's own app doesn't provide the tools they want/need. To the point of the other person who responded to you, Reddit has absolutely dangled a carrot that does nothing in an effort to seem like they're being helpful.
