Cheating can be one of those "I know it when I see it" things that can require judgement from experts in difficult cases. Competitive chess players are the best ones to judge what constitutes cheating in chess, for example.

But what this startup is doing is the Wikipedia definition of cheating, with no reasonable room for debate:

Cheating in online games is the subversion of the rules or mechanics of online video games to gain an advantage over other players, generally with the use of third-party software.

And it seems pretty obvious that they know what they're doing is wrong. They just seem to be very determined to try to push forward, and seem to think they have cleverly concealed their bad behavior, hence the cover story bs about "coaching" when they clearly know what anyone would actually use their software for.

I'd guess that they also rationalize selling cheats because others do it, which is obviously no ethical defense at all.

YC probably needs to be the ones to set them straight, since they are in a position to do so, and have explicitly made it a goal to avoid funding unethical startups.
