Sure, I can see that maybe if it's your best vendor and their product makes you a lot of money you can tolerate some poop on the floor occasionally... ...but if you decide to ban them I don't think anyone would ever consider it an "abuse of power" would they? Your service came with an element that's detrimental to my own... that seems like reasonable grounds for a ban. I think this starts to approach conversations about how big is "too big." If a company or product is so large that a simple ban for bad behavior can be considered "abuse of power" then maybe that product represents too much of the market.
