-Lying-through-the-teeth PR fluff
-Ignoring negative criticism.
-Disregarding customer claims of being unfairly banned.
-Not offering refunds to those who lost money on the RMAH
-Forcing customers to jump through hoops just to play the product they bought
-Disregarding account hacks
-Blaming customers for their faults
I have yet to see any of them lying, other than people around the forums twisting words and reading things into statements that aren't there, and then "Calling them out on it"
I'm fairly sure they haven't ignored negative criticism. They're making changes as we speak. Just because they didn't individually acknowledge every single complaint that every single player has made doesn't mean they're ignoring you.
They haven't disregarded anything. Just because someone told you "Blizz banned me, i didn't do anything wrong!!!" doesn't mean that they're telling you the truth. False positives occur from time to time, but they're the exception, not the rule. Not to mention, it's not a public matter, it's a matter between you and Blizzard, no one else.
Offering refunds to people who lost money? Are you kidding? Why would they do that? They didn't get take your money, the seller did. And, you don't get refunds from a bad stock purchase. You just lose the money. With regards to the cases of the sellers "losing money", they haven't lost anything. They just didn't get paid. Which is probably the buyer's fault (you can thank all your friends who were here telling people to do chargebacks for that)
Forcing customers to jump through hoops? Well that depends on what you mean by "jump through hoops". If by that you mean use a standardized OS, have a decent computer, and a decent internet connection, I don't think it's so much to ask for. Most gamers already have all these things.
Disregarding account hacks? How have they disregarded them? Security is your own responsibility, and Blizzard will "rollback" a hacked account if it's verified. It's just a ticket away.
On to your last point, blaming customers... this is just stupid. What are they blaming us for? The assassination of JFK? Failure to bring peace to the Middle East? What? This point just made no sense at all.
So, I suppose that, yes, I'd like to see some actual, empirical evidence of them "treating their customers like crap"
