> I doubt I'm the only person here who has ever made an alternative client for something before.

I've been on both sides of the issue by authoring unofficial clients, and battling abusive unofficial clients to services I run. The truth is, complete carte blanche for either side is untenable. 99.99% of well-behaved clients are tacitly ignored, I'm not against those that deliver malware, or bypass rate-limiting having their day in court.
