Why are Mark Cuban and Jerry Jones the most hated owners in sports?

[NBA Fan]

in a recent poll they asked which sports owner do you hate most Mark Cuban was number one and right behind him was Jerry Jones I can't understand why Mark Cuban is he completely turned around a franchise, well he is kind of a douche and Jerry Jones well he's Jerry Jones whats there to hate about him and did anyone find it ironic that they're both owners of Dallas teams
