Both sides are insane. Sumz made some irrelevant attacks, but Wizzard's response about "I could have just wanded it" probably goes further to support Sumz'/Ronin's argument than anything else. Also I was in the server when Sumz/WIzzard selected the design for the power plant and I recall Sumz saying that he would not do any cylindrical parts. Thus the lack of the stack.
On the other hand, I tend to agree with the idea that a USSR server should be a USSR server. If someone (See : Loserhero) is hosting their own server for their own build and have the admin set up differently, they can just not fly the [USSR] tag in the server name. The tag should mean that the server is run for the clan, not just that a clan member happens to be hosting it. Maybe that's just my view though.
See also; the idea of "I'm hosting MY server FOR USSR" is contradictory, it can't belong to two different groups/individuals at once. Wizzard, as host/member of USSR, could have a say in the running of the server/build and probably a bit of weight since he is the host, but he shouldn't have a final say on things.
