I have noticed this for a long time. Don't forget the cash factor. People are in with CIG for hundreds to thousands of dollars, some have interests in grey market reselling and don't want to be left holding a stock of worthless ships. There is huge emotional and financial bias at play when it comes to CIG and Star Citizen and while its not a cult per se the behaviour of its most fervent backers is the definition of cult like behaviour(my leader can do no wrong and will guide us into the light).
As for Frontier and ED, backers by and large have at most a couple of hundred spent on the game and usually much less so they get the usual expectations and criticisms heaped on them as any other game. They don't get special treatment.
Odd isn't it.
You would think being $10,000 into a game, an individual might be seriously critical of any business or design decision. I know the less invested I am in something generally the less I care about it.
