It didn't mention the inconsistency of this change with standard representations in leading software that has been that way for decades. It didn't ask the people responding if they had actually used linear-gradient in a site yet (which might have informed their answers). You presented it as a change you were leaning towards making, and as though there would be no problems with making such a radical change now. That's biased.

Something that radically changes the look of every Web page currently using degrees to indicate direction in a gradient? That changes all the tools that have already been created to create cross-platform CSS3 gradients? That is hardly a small detail.
