It's controversial because there is nothing actually rude about "it's broken! FIX IT!!!" message and when people are truly rude while asking for support it's because they are frustrated with the service they wasted time on and paid money for. Mocking frustrated users is just crazy.
Also if you have them on a tiny service it's likely an indication of poor user experience: poor user interfaces, poor performance, poor documentation, poor reliability, etc.
It isn't rude? How not? I guess we're having a cultural clash here, otherwise I don't understand.
When I'm frustrated I try to collect myself and be mannered. It's not an excuse. Communicating properly not only makes everyone lives better but also allows better understanding. It's more efficient.
I think it is rude. When it was not for the business I worked for I would just walk away from people like that, and yes a computer tech that happen often to me while I was not working.
