Is there a TL;DR of some of the key reasons for contempt against Shad etc?

Hi all,
I've watched Shad on and off over the years, he's definitely become increasingly whiny about stuff but I stumbled across this page and wondered if anyone has or can list the key reasons that other people don't like this guy or his affiliates?

I feel like I read something regarding screwing over or being unsupportive to his brother iirc (Jazza) Alongside him whining that it's all YT fault and not his for not swapping up his style.
