What I mean is this: the fanbase is too diverse. And none has the right to claim something is the wish of the 'fanbase' just because they think so. Because there are others within the community also being fans who disagree. It is not from within that the fanbase general opinion can be stated. However I utterly dislike being told, my opinion is not valid, because fanbase thinks differently. Why am I or my opinion excluded from fanbase? That is what was spoken up against.
(This also is valid the other way. Just because someone doesn't agree with me, they still can be part of the fanbase.)
Your opinion is valid, it just doesn't carry enough weight to prevent the creation of a consensus among the fanbase. Bioware aren't concerned with what every single individual fan thinks (you, me or anybody else); they're concerned with what the consensus is. They already know what that consensus is, but they have to weigh it against what the rest of the market (potential customers) think too.
In the broadest possible terms, there's a pretty clear distinction between what these two groups of people want. The established Bioware fanbase may bicker about every single detail, but it is self evident that they enjoy Bioware games and would like them to continue making them. It is also self evident that the much larger group which doesn't buy them (but may well have bought Skyrim) would like them to make something more to their taste.
Bioware has the almost impossible task of trying to satisfy both of these groups, or they have to choose one over the other, or they have to gradually bring them closer together (which is what they've been trying to do since at least Mass Effect 2). They've been weaning the established fanbase on to action combat and multiplayer, while at the same time trying to show the wider audience that narrative and some tactical elements can be fun. Judging by the relatively stagnant sales of their games, I'd say this approach has had limited success so far.
