It's completely valid and reasonable to be upset that Nintendo poorly managed Wii U software releases, in many respects. Too many droughts, and they missed the mark at launch, having mediocre software.
But I don't understand the attitude of "I had a bad experience, so I don't want anyone else to have a good experience, either" = "I'm not happy with Nintendo's Wii U releases, so I don't want Switch owners to be happy with these games, either."
That doesn't make any logical sense. Why do you care about someone else having the opportunity to enjoy a game that you yourself played?
