The only thing I've ever been shown about "insults towards the fans" was a lot of extremely contrived bullshit, mostly just taking things out of context, or a word's definition given the context, and straight up misinterpreting what is said. The most logical point to make against it is that no one from either of the two companies (NT and Capcom) would go on record to insult the consumers of a product they're trying to sell, because they would be out of a job minutes after having made a public apology. Tell me how definitively insulting fans would get past two entire companies-worth of people, and wouldn't have been picked up as a story by every gaming journalist in the world...y'know?
I'm pretty sure that they have never openly insulted anyone and it's just people trying to stir up trouble.
