So to suggest that people that switched did so out of "blind loyalty" to either WotC or the D&D brand, is pretty damned far from the mark.
But it's as far from the mark as much as it is you implying that NO ONE switched out of pure brand loyalty because we know that that's not true. There are people who are blindly going to follow WOTC / D&D no matter what they do.
There have been people here on this board during the switch to 4E who have pretty much said this. So no it's not far from the mark at all.
Now is that the consensus of the majority of 4E players who knows? But I can tell you that there are some folks here that are pretty dedicated to 4E and in their eyes WOTC and the 4E designers and D&D can do no wrong.
