I was talking to my cousin about this last night, and he made a pretty good point.
Why did they do another RTS? They already have an RTS that they just finished. I mean if they had done a game from a different genre, which didn't seem in direct competition to the game they just *made*, and which people were, in general, pretty unsatisfied with, it would be a different story.
The fact that it had so many similarities to PA, seemed to fix a lot of the problems with PA (multiple races and flat maps), had such a similar art style to PA, and was of course the same genre as their original game. I think to most PA backers, it was just a slap in the face. It's like, "Let's make an RTS to replace the failed RTS we just made."
I'm sure that wasn't their intention during the development/Kickstarter process, but that's how it came off.
He made a pretty good analogy. PA is like a girlfriend that you're already in a relationship with, HR is like her sister who is trying to flaunt herself and get your attention. Why would you leave the original girl to be with her sister? Seems like a betrayal.
