There is no group of witnesses.
Let me repeat: there is no group of witnesses.
You might think that way, because somehow they all agreed on certain subjects, but that's only from the outside.
The witnesses are 20-50 individuals who worked together on governing the chain. Those 20-50 individuals have different world views and opinions on how things should be run. There are often discussions and disagreements on certain subjects. Pretty sure that isn't the case with Justin Sun and his sockpuppets.
Just because you disagree with the consensus that witnesses came up with, shouldn't mean that you can just call witnesses to be a group. Again, we are all individuals.
