Their problem with Technicals, fundamentally, is that they're a bunch of children that hate people by tribalistic association, rather than merely considering what a person actually has to say. Technicals has, at many points, credibly attacked significant figures in the community, as well as credibly defended other significant figures that the community has deemed persona non grata and tried to destroy.
It doesn't matter to them that what he's saying is provably true and logically the better answer to the situation - they made their judgments of these people beforehand, and so rather than allowing him the chance to vindicate them, they decide before hearing what he has to say that because he's associating with these people, that he must be a bad person.
It's a philosophy that exists to insulate and be as inflexible and unchangeable as possible, due to the way that it conveniently locks all counterpoint behind a convenient shield of morality. Simultaneously, it shuts out the ability for change to come from within, since anyone among them who dares advocate for the opposite viewpoint is lumped in with the opposition and similarly vilified.
This is also why no significant voices in the community dared speak up for Hax$ before he died, because even though many of them were on his side, they were all terrified to be ejected from the community in the same way, because speaking for him would make them guilty of all of his crimes by proxy in their eyes.
