It has nothing to do with me liking your opinion or not. It's the way you project your opinion as fact and how you misrepresent the true facts. You can buy whatever you want to for yourself and even recommend stuff as long as you aren't slandering the product you don't personally prefer.
As far as why people pay more for the same or similar tech and performance from nVidia, like yourself? Don't know. It makes no sense to me.
As far as my strawman, there are people who hook other components to their PC monitors. That's why they often offer more than one input of a certain type, like multiple DP, for example. Unfortunately the Gsync module only offers a single DP input.
Some Freesync monitors even have HDMI 2.0 which AMD cards don't even support, but nVidia does. From all of the negative feedback from nVidia supporters about AMD cards not supporting it, it must be an important feature for nVidia users. Since no Gsync monitors have HDMI 2.0, seems like these nVidia users clamoring for HDMI 2.0 might like these monitors.
BTW, that last paragraph was a strawman, since in reality HDMI 2.0 derves no useful purpose.
