The number of abysmal attitudes they have, while managing to avoid actual consequences on the market, is staggering. It's an interesting case study in the amount of pain that can be inflicted on customers when you do it the right way. I am "only" at two automated blind charges right now, On the other hand, I have one of my own customers extremely angry because he had to wait 14 minutes after his purchase for us to call back and respond to his tech support query. I of course refunded him, telling him we were so sorry we hadn't been able to support him in a timely manner (in reality, I would have paid not to have to deal with him :-) ) and yet he keeps coming back.
The sad truth is that an automated support, hard to find, made of automatic canned replies (those are always timely, barring a spam filter issue), is the probably the best strategy to deal with today's consuming masses.
And to top it all, I have already had requests for our OS X app to support the new "full screen mode" of Lion. Well, the last time I wrote a full screen app must have been in 1995. One never stops progress....
