I'm getting a little distressed by this sort of common perspective among gamers in general and roleplayers specifically. It seems that more and more often that a player, who has no real authority in design or decision making in a game, feels that changes to the game that do not mesh well with their own perception of the game consider it some sort of personal attempt by the actual creators of the game setting to ruin their day, personally.
CCP and every other developer are not setting out to screw you. You signed up for the potential to screw yourself. For every change and development in the game's storyline you are presented with a myriad of choices that boil down to two overarching paths. You can either embrace the change and work with it, incorporating and building upon it for your personal roleplay. Or you can hit it in the face with a shovel, rant and rail against it and embrace your opposition to the change as part of your personal roleplay.
You get to make your story in EVE.
You do not get to make EVE's story.
CCP gets to make EVE's story.
CCP does not get to make your story in EVE.
Do I think it that CCP makes personal attempts to ruin player's gameplay? Well, yes. A company which makes a game designed around the ideas of griefing, robbery, theft, and violence probably does occasionally indulge in some griefing themselves. That's just the nature of the beast. I certainly couldn't say that they are doing so right now, but some previous events did seem pretty close to that.
And yes, signing on to a faction is essentially signing up to be screwed over. However, I think you are confusing the fact that that happens with the idea that one should accept that that happens, no matter how it happens. In general, when we accept the specific fictional guidelines of a universe (say, that the Amarr Empire operates a certain way, that there are no magic powers, etc), it's probably reasonable to expect that Magic Psychic Zombie Space Princesses with Superweapons won't get pulled out, just as it is also reasonable to assume that CCP won't decide tomorrow that all capsuleers are ponies from the MLP universe.
CCP certainly has the right to do whatever they want with their product, just as you have the right to pour maple syrup on your head and lie on an anthill. But that doesn't mean that others are required to think that it's a good idea and not complain. In this case, to extend the analogy, quite a few Caldari RPers spent quite a bit of time styling the hair and making it look better, while still along the lines of what CCP had created.
The problem with embracing Eve's story is that CCP has been busily creating more and more disconnects between what was, and what is. This means that those who invested in the RP scene back then now have to decide whether to ret-con and adjust their characters (hey! actually, we love dictatorships after all!), find something else to RP with (and how long until CCP blunders through that?) or toss out RP altogether (screw you guys, I'm going home).
So no, it's not as simple as "adapt, and HTFU". CCP has shown no respect for the fictional setting it started out with, and now older players have to figure out how to, essentially, be horrible writers who don't care about continuity, characterization, or realism.
