I can understand people being annoyed at losing the online service, but I think Sony needs to be cut a little break here. Like it or not at the end of the day they're a victim in all of this. I'm sure they take no joy in having their service down - upsetting their userbase, developers and losing revenue for themselves.
Now I agree that they could have been more transparent about the whole situation. Whether the amount of work they're doing is nessacary or not I dunno, but some people here are overreacting big time :-/ acting like Sony took the network down just to piss us off.
I'm one of the last people here that would go out of my way to defend a huge corporation but there's a clear difference between things they should be criticized for and things that are out of their control. Removing backwards compatibility - bullshit move, removing otherOS - sucks for those that wanted it, however....getting hacked by an outside source? not something that could be helped.
