So, you are saying they are biased? So essentially you are agreeing with me on why the sample is worthless.

.
A sample that is generally biased IN FAVOR of the dev and the game is largely voting against one of their design decisions.
Take it as you want, but it doesn't seem to paint a flattering picture of the general feedback about this specific topic.
I'm confident the results would be even more hostile toward the changes Larian introduced if the context was, say, a "Dungeons & Dragons community".
Frankly I can name pretty much any minor or major forum I lurk or frequent and the outcome tends to stay pretty much the same across the board: most people don't like several of the changes Larian introduced and tend to be very vocal again it.
Sometimes so negative that I'm the one who has to play "good cop" and suggest to them to tone down their rants, pointing that "it's not all bad".
Incidentally, in case you missed, I also happen to disagree with a lot of what the OP said here. That doesn't mean I have to be in denial about how representative the survey he posted can be.
Now, we could have an argument about how much that survey ACTUALLY supports some of his claims, but that would be a different topic entirely.
