It feels like an overly sensitive approach. We're talking about the final of the CIS region. This is probably the most significant sporting event in recent times. Maybe we can put aside grievances? At worst, there will be a chance to settle things in person, not behind a monitor.
Where are the grievances? This person is really ruining the final with their statements, or am I the only one who sees it? But it seems that because of them, several people have already refused to participate. Maybe it would be better to find a more adequate organizer? Would you be interested?
