The single player forums are mainly positive. As they recieve a the main focus with each patch there is a sense of optimism even when features aren't added as soon as hoped. To say TW doesn't give a **** is a bit harsh.
I am firmly of the belief that multiplayer is heavily down-prioritized right now to the benefit of singleplayer. Since TW refuses to outright say so; if you play only multiplayer, it feels like TW doesn't give a ****. The truth is that multiplayer still recieves attention, it's just very very slow. I can't answer for those that only post to complain, but I see many genuine constructive suggestions being posted here and we know at least someone from TW occasionally reads them. I also believe that multiplayer will become a greater focus once the singleplayer is more finished (currently it is very lacking). Possibly even after the full release.
We have already payed for the game, TW is still developing it and people are still playing. There is no need to trow our hands in the air and give up on a game we've waited many years for.
