I like the Wii U. It has good games on it, and the gamepad just needs some adapting. Once you learn how to use it, It is easy. (Except for the flying controls in LEGO Marvel...)
My answer to the OP's question is just people are having trouble adapting to its new controls or they are just dumb fanboys and can't "betray" their favorite console(s).
I hate the people who spam things that are against what you think is cool, and resist from stopping when asked kindly to stop. Sometimes they even lie to prove their incorrect points. This is something I found while listening to Legend of Zelda music. (Loz= Legend of Zelda, just so you know what he is saying.)
thecorrectgamer commented "LoZ: $350 regardless of console. CoD: $20 or less on every console. LoZ: Graphics look bad (unless on LoZ TP or above, but that's only 240p). CoD: Graphics range from 480 to 1080p. LoZ: It's obviously a rehash because it creates 2 games per year, and both games will look the exact same except the cover and name. CoD; Has a generous amount of games, and each game is different entirely. - correct gamer logic"
I checked out this guy's feed, all he ever does is spam his negative assault on Legend of Zelda videos. He even posted videos of his fantasy world where world peace is solved because LoZ was ended, which were animated with a pre-made animation and computer voices.
I wanted to throw a truck at this guy.
Where I put italics is where he swore, but I changed it.
Torterra is my oldest pokemon, Started from Pearl version, 2 years later I finally beat Pearl, Then he migrated to Soul Silver, Stayed there for a year, went to black, Stayed there for a year, and now he is in Black 2.... Yeah, He Is my Warrior...
Also, Fun fact is that my Typlosion is faster than my Latios, which means he is faster than a jet O_O
