I think both of those would be better than their actual response, which was accusatory and hostile.
This is actually interesting. I think there's probably a huge opportunity to communicate with your customers in this case. There's got to be a way to engage while respectfully disagreeing.
If you're dealing with a number of people who aren't your customers and were never likely to be, then you have a different problem as the presumed customer relationship isn't there. In this scenario you're dealing with people who don't care about your product and wouldn't buy anyway but mostly want to see you knuckle under. Engaging them as customers is a fundamentally misguided decision.
