Somehow the entire human population has decided to pretend that the Switch is a home console akin to Xbox and PlayStation consoles, even though you often hear that the Switch's biggest strength is its portability.... I mean can't people see how seriously flawed that categorization is?
Regardless, PS4 actually had a sell-through of 20.2 million units in the year of 2017, so the main premise of this topic itself is incorrect.
Here are the problems with your post:
1. No one is pretending the Switch is a home console akin to Xbox and Playstation. You didn't read that in my post; you made that up.
2. You found some other site with alternate numbers, give a big piece of bubble gum! Then come back here, re-read my post... carefully... so you don't again miss the fact that I'm citing our site, VGC, for numbers. These show 19,808,528 sales, not 20.2: https://www.gamepur.com/news/ps4-sold-202-million-units-2017
I describe myself as a little dose of toxic masculinity.
