The main point is that Wii U sales do not reflect the size of Nintendo's fanbase, nor do Wii U sales represent Nintendo's most important customers. That's why Nintendo doesn't need to cater to Wii U owners. That console is dead and over. Nintendo has to cater to Switch owners now.
I think the good fans are those that like it when Nintendo innovates - especially with NES, Wii, Gameboy, DS, and Switch.
The toxic fans are those who praise the failed consoles like the second coming of Jesus, and then disparage Nintendo’s more groundbreaking consoles. The Gamecube and Wii U were the bad consoles, one tried to be a purple lunchbox Playstation, the other was tried to push an obtuse oncept (assymeytic play) which screamed gimmick to cover up the limitations of the Wii U.
The one in the middle is the N64 as it was a mixed bag of good and bad - the idea of full-3D should be praised: but the idea of using those bulky expensive cartridges was absolutely terrible. It didn’t stop games from having load times, but it did stop games from having good music or proper graphics due to the highly limited space for textures. Also, the audio seems to have taken a hit since PSX was WAY better in this department; even SNES games generally had better music.
I don’t think that Nintendo fans who didn’t like the Cube or Wii U are necessarily outside of the core of Nintendo’s fan base, they are just outside of the toxic base who are generally pretentious in that they will always refuse to like anything new and successful on a commercial level, but will fanatically worship it if it is a failure; why I can’t stand most Cube fans. They claim to be the hardest Nintendo fans but are much more shallow in that they are actually praising it for its similarities to PS2 and ignore the fact that it is the only console that really lacked any kind of Nintendo’s typical innovative approach to interface and gameplay advancement. Wii U’s approach to make things more bulky and convoluted, while a change, is not the typical simplifying/intuitive addition that Nintendo generally does, it only made playing games more of a hassle because of having to look down at a second screen, unlike the DS where you could look at both screens at once and use one as an effective controller.
I describe myself as a little dose of toxic masculinity.
