If you walked into a bank to open an account, and the teller said "good thing you didn't go with those fucking morons across the street", you'd be shocked. You wouldn't trust them with your money. Here in bitcoin land, you can have a hardware manufacturer or an exchange owner call its customers fucking morons, and nobody even cares.
I know BFL has behaved in ways like that, but I don't recall any exchange operators that do. Ah, wait, MPOE-PR can be rather biting, true.
I do agree that sometimes exchange operators and issuers, including myself, can be too informal at times. Some of us are responsible for managing millions of dollars worth in portfolio equity, and you are justified in wanting those representatives to act maturely and responsibly. It's something I try to think about as often as I can, but admittedly I can be susceptible to good trolling and frustrated with some forum "superstars" at times. Know that I am making an effort, and I assume people like Burnside, Ukyo, and Lightbox are doing the same. Even, Deprived, the Grim Reaper of bitcoin finance, can show emotion and lose a little control at times.
I have been running my own successful business for most of my career now, and my responsibilities have included interfacing with clients, customer service, and sales, even though those are not the core services I provided as a business. As the business grew, I was able to focus more on what I was best at, and leave the other aspects to specialists. In that sense, I think part of what you are seeing in bitcoin is small business style management and behavior, in an industry that has been traditionally one of big businesses. You'd never see things like the programmer being the CEO, PR, and CS rep for a financial service in the "real world".
There is plenty "wrong" with how things work right now, but I do think it's improving before our eyes. More transparency, scrutiny, and raising of standards will come, no matter how much kicking and screaming it takes.
