I couldn't remember how people reacted about PS4'S first year, but the difference is that the Wii U only sold less than 14million, while the PS3 have sold over 80million. 

In my opinion it makes more sense for Nintendo to port Wii U games. And it also allows us to play those Wii U games and 3rd party games on the go like never before. Obviously Nintendo and third party devs sees this as a good opportunity to port games. 

Sales of previous console doesn't matter. 7.1 billion people didn't have a PS3 so you could say the remaster would appeal to those people :)

Like I said earlier PS4 remasters feature better graphics and framerate for us to play the superior version of the game like you want to play the portable version. See how it goes. There is no defending one and criticising the other.

So what is the problem here? The PS4 got those ports early on, but now it is getting and have gotten lots of awesome games = Very High Sales. The Switch could do the same. And maybe that is why people are defending it. 

I think his beef is that he feels like Nintendo is getting a pass for doing ports while Sony didn't.  

Since I was one of the people who made those criticisms of the PS4, let me highlight the differences. The PS4...

A. Didn’t have loads of quality exclusive experiences in its first year to justify a year one purchase. I bought a PS4 on launch day, and a year later I was playing both an Xbox One I got as a Christmas gift and my Wii U far more than it. The only quality exclusive that system had year one was Infamous Second Son. The Switch, meanwhile, had: Splatoon 2, Mario + Rabbids, Super Mario Odyssey, Xenoblade 2, and Kirby Star Allies will be missing the year one deadline by mere WEEKS. 

B. Isn’t portable, meaning that PS3 ports to it inherently have less value. If you value portable experiences like I do, then the Switch is great because it has LOADS of exclusive portable experiences. Zelda Breath of the Wild, Mario Kart 8 DX, Sonic Mania, Doom, and Skyrim are all GREAT portable experiences and practically transform how I play them versus regular console versions. And the same is still true for these upcoming console ports.

Ports of games like Last of Us on PS4 didn’t do much for me, despite their quality, because I had already played many of these games in the exact same fashion just a few years prior, and being able to play these games in the same way with slightly up-ressed graphics didn’t really mean much to me. So far as I’m concerned, that’s what backwards compatibility was for.
