First replies get a lot of attention. Everyone reads them first, and if it's a "controversial" take, people react, and then the thread goes off into the woods, with everyone responding to that first reply, rather than the OP.
I see the first reply ("Switch isn't a console") as a weak attempt to exclude the Switch, as if it "didn't count." It's part of a console war mentality that needs PS4 and Xbox to be the "big guys" and wants to sideline Nintendo as something that appeals to "a different crowd" than "us." It's been going on a long time and will continue to go on. It used to be based on "it's got kiddie games." Now it's "it also functions as a handheld."
I was a part of that myself, a few years ago. I thought Switch wasn't "really" competition for the PS or Xbox, because it was appealing to a different demographic -- Nintendo fans and the mainstream market -- whereas "core gamers" gravitated to PS4 and Xbox. It's sort of an elitist mentality that wants to exclude Switch from the "club" or minimize its success.
I own a Switch now. It's a great little console. I think its success has everything to do with the great games available on the system. Personally, I use it 100% docked.
Those sales numbers are extremely impressive, especially when you consider how sustained the momentum has been. Switch is more expensive now than when it first released, and people are buying it in droves.
