It's all about "if somebody has something I don't, I'm worse off as a result". It's the same psychology that leads to people telling a lunch lady she can't make such good food because their kids' lunch-lady-prepared food isn't as good[1], so, therefore, their kids are worse off than they would be with everybody having crappy food. People try to justify it as "we should all be equal" or some garbage.
From the link: "Update: The day this article was published, it was announced that Eriksson will be able to continue baking her own bread and providing healthful vegetable options. The incident has been called a 'misunderstanding,' according to Swedish news source dt.se."
