What leverage do email companies have? They do it by having enough scale to maintain a more personal relationship with the email providers (goog, ms, apple, aol, vz, etc). And it's not like Insta banned this guy because of some nefarious plot. They want people like him on his platform and want to be able to remedy accidental bans. They just suck at moderating. An intermediary can help them and they'd be glad to deal with them. They don't need leverage, just credibility.
