As of immidiately prior to him being blacklisted from DT1, he was voting for others in his trust list to be on DT1.
And then he stopped voting and removed himself from DT1 at the same time. If he had removed himself from DT1 and continued to vote for others, you
may have a point, but he didn't so you don't.
If he was forced out of DT1, he would presumably be unable to vote via his trust list as well. Removing his trust list would only remove the possibility of someone not showing up on DT1 when they should have if his trust list votes were to count, and would reduce the chances of anyone asking any questions with substance.
It also looks like he does not
like being questioned very much. What he posted is also not proof of anything, it does not show context, especially if there was communications before his alleged message he sent asking to be blacklisted from DT1.
