At this point my advice would be for you guys to just leave it be. Stand up and walk away from the computer and go watch a movie for the night. You've made your call on this issue, you have unspecified "plans" and unless you care to reveal them or you care to change your stance on this issue there's nothing more to say or do here. You just need to let the anger blow over.

You don't gain anything by further antagonizing users at this point. And from your stance here - you don't actually want these people as users, correct? Essentially you've decided that these users are so-called "devil customers" - they're not profitable and you want them out of your clientele.

That's why you're essentially hardforking away from their hardware. So their opinions are no longer relevant to you, are they? As such this is literally a no-win move for you, the only thing it can do is hurt your business's image.

Just walk away, this isn't a good look for you guys.
