"when they didn't get what they wanted" you make it sound like it was a flick of a switch, it was a gradual shift as more and more people got exposed to how little Taleworlds actually wanted to work with the community to make the game "the community" wanted. Doesn't matter how nice or nasty your community is then, if you aren't even paying attention to them.
For christ sake to name a few examples in recent memory: Internal combat tests with the best clans in the game were held, crush through was tested on the last day of this testing, overwhelmingly negative concerns by everyone involved but they still pushed it into the live patch and refused to remove it for months. Throwing weapons spam was in full swing last summer, they removed a large amount of throwing weapons at the communities repeated request only to return them in a patch earlier this year(no one asked for this ****) in a worse way by giving them to classes that can triple spawn with little gold saved. Both of these leave a bad taste in mouths of the small community we have left.
Now there is a line you don't cross, and some people certainly do with death threats and the like, but that doesn't represent the multiplayer community as a whole. By all reckoning the current multiplayer should be stone dead with 0 people playing but a small minority of people keep playing because they want and hope for the game to be good.
