If there is widespread election fraud (which has not been proven and includes an undefined term used as a negative persuasion tool "widespread" anyway) then that is the coup attempt you refer to and their platform is host to uncountable instances of people claiming a certain person has been elected and now there will be no counter information for people to consider the alternatives.

Yes, that's true. Again, I don't think this is about any higher principle; many people just aren't willing to maintain editorial neutrality with respect to a coup, and I don't think it's reasonable to expect them to.
