It seems like he is not allowed to criticise the actions of these groups. I will admit though, he crossed the line the other day when he made the takfir. 
He criticised some Sheikhaal mooryaans that fought under the USC banner when they were given Hawiye sheegato status. He called them out and rebuked them for hate speech. In this video, (first vid) Sheikh Dabcasar has sparked outrage amongst some that actually believe their clan is saintly. I am not excusing his provocative language or his blanket generalisation/mischaracterisation of Sheikhaals as munafiqs ( which is probably akin to hate speech). I am just showing you guys the stupidity and the hypocrisy of some. This guy claimed (ridiculously) that his clansmen are infallible, and then claimed that he can't would insult an entire clan, only to the opposite only a minute later. The inconsistency
He sounds like half of this forum lmao. I imagine many of you guys get this angry when you read FKD against your clan, I have seen the way you guys post, frothing at the mouth with rage.
Ilaahey ha soo hanuuniyo.
