The problem is these "admins" are acting on behalf of the various Wikipedia communities as a whole.
How WP is run, is supposed to be decided by the community.
If these "admins" actually administered the underlying infrastructure as well, this would be a non-issue,

The WMF is entrusted with this task, but the WMF is betraying the trust of the community.
I think I might ask for my donations to be returned to me, since they are no longer acting according to their mission.
