Honestly, I think between Ciarente and Graanvlokkie, the issue was hit perfectly. Certain issues, especially relating towards matters of power and the abuse of such, can get to us (I refer all those here to the "Things in RP that OOC disturb me" thread from a while back). These feelings, at times, may effect how we react not just to characters who take those views, but the players behind them as well.
I'd also postulate that Amarr and Sansha at least may come under more fire for being "evil" because their evil is easier and frankly more believable to play. An Amarr can say he owns (or tortures/kills/captures) lots of slaves, and by and large the OOC community response is "Well, okay. You're Amarr." (Yes, it's a lot more nuanced than that, but I'm generalizing.)
When a Gallentean tries to play their brand of "evil" - i.e., freedom at any cost, unless done extremely carefully it can easily provoke responses ranging from "Godmodding!" to "Capsuleers don't have any roles in that!" to "Meh." etc etc. (For example, try claiming you've effected a massive effort to remove hundreds of thousands of dissenters from the State, some from Provist prisons. I suspect there will be just as much a response of "well, how did you pull that off, huh?!" as actually going along with the RP.)
Or I could be pulling at straws.
And yes, CCP needs to publish these sudden changes in PF, dammit. And rationalize them a bit more.
