It defeats the whole point of this system if those who criticize things are simply labelled trolls to be considered bad corporate citizens.
Chairman Mao called for a hundred flowers (opinions) to bloom. He invited criticism of the system. At first people said "It's a trap" and no one seriously criticized, only token critiques were offered. Perhaps similar to modern suggestions about policies for washing mugs, what sort of free coffee should be available in the breakroom, or if there should be a third bathroom for transgender. Things that don't represent any serious challenge to the existing order.
Then Mao made clear he really wanted criticism of the system and no one should hold back. So people started talking about what was wrong, and telling the truth about the failures of totalitarian communism. These criticisms were considered "absurd", the people were labelled trolls ("rightists"), rounded up, and executed in the Anti-Rightist Campaign.
If you want honest feedback from people, calling them trolls, with the implicit threat that criticism is wrong and should be eliminated, is not the way to get it.
The only way to have real honest feedback in a small group is to listen sincerely, and eliminate punishment of dissidents. This can only be done through trust, which is developed slowly and with difficulty. 99.99% of the time when corporate says to trust them and it's OK to make suggestions, they are lying and intend to identify and destroy anyone who seems to be a threat to their agenda.
I guarantee that if we collect a list of all the actual "troll" things that were said, most people outside your system will see significant numbers of them as representing valid criticism, and therefore unmask the truth that labeling the criticism "trolls" is an exercise of power to eliminate minority dissent.
