Three points.
Firstly, I'd argue those people have been somewhat vindicated with Leicester being relegated and the other two in a standing sprint to nowhere.
Secondly, it's rarely just praise. Often it's used to bash our own side so it's understandable why it rubs people the wrong way. Even with Newcastle we've seen praise for them used to diminish the work Arteta has done and to mock 'the process'.
Lastly, I've always found it completely normal for fans to show favouritism towards their own team or struggle to praise others. So yeah, fuck Newcastle, fuck objectively and most of all fuck Atalanta.
