What's up with the sassuolo and udinese hate?

Under most of the posts talking about the relegation battle I've seen on instagram there are comments of people that are happy that these teams aren't going well, and I genuinely can't understand why since I've never seen anybody hating on these teams until now

I've never seen something like this, even in previous years with other tean, and it was definitely not expected towards a team like udinese that has a good football tradition

What are your thoughts?
