Hey man, I don't really care if he cares either about my opinion either.
He is making both MMA and himself look bad with his commentary, but it is what it is.
He's the one that looks bad to anyone that knows MMA by talking out of his ass. And in turn, his employer also looks bad.
Now, if I am a viewer and I see him talking out of his ass on MMA, I am immediately going to assume that he must just be a bullshitter when it comes to all sports. So in turn, I won't want to watch him, and I'll switch the channel whenever his show is on.
I'm sure I'm not alone, I'm sure there are tons of people who think his MMA commentary is bad, so they will also not watch his show. This means he is turning away potential viewers with his nonsense.
