It's not, but it's completely reasonable to be frustrated when a business partner (which they certainly were) changes their approach without adequate notice and without appearing to care to make any concessions to continue the relationship. Especially when you are being misrepresented publicly (that last part was the point where the apollo dev actually became adversarial: previously he was simply saying it didn't look like he would be able to continue with the app). The majority of actual rage is coming from the users who are having an interface they liked taken away from them, especially because they perceive (quite reasonably) that this is for money-grabbing reasons and not for the long-term health of the site. I think reddit would have had less blowback at this point if they had outright banner 3rd-party apps like twitter did, instead of spending the whole lead-up claiming that they would not be doing the same thing as them, only to effectively do the same but less honestly.
