I did not back this, so I personally am not invested in it. I was interested, but they did not explicitly state it was DRM-free -- at least not that I could find -- so I decided to wait and see.
A good decision, as it turned out.
Anyway, it seems to me that the developers do indeed have a communication problem, but not in the sense those defending them are trying to imply:
* Clearly, they promised an offline mode: Else why would they announce that they will not be able to deliver it?
* Clearly, they knew relatively early on that it will not happen: Tying everything in your game into data that must be retrieved from central servers in real time is not the kind of thing that crops up on you in the last minute nor the kind of thing you might not notice.
* Clearly, they knew it would not be a popular decision: Else why did they delay announcing it until practically the last second?
So, fundamentally an evil thing to do.
Now, I'm not keeping a list or anything, nor would I boycott anyone over this, but I will certainly not believe any promises from any of the principle developers involved, myself: show me the goods, and I'll buy if I like them.
How you decide to handle it is, of course, entirely up to you.
