Although, yes, he mentioned squad channels and that section of the post does need to be dismissed, theres still plenty more that he mentions, and very good points.
He's pointing out that, although most of us are grown guys, we get shot down and automatically come up with excuses...
'****in aimbot' 'D*** cherry picker' etc...
He's complaining about gameplay more than anything, which I think is somethikng that needs to be assesed...
I do believe there should be rules ON gameplay i.e.
'Get shot down? Don't freak, click the runway button, and go hunt them down.'
