Reverted change
I have reverted your removal of the category from United Russia for much the same reason as above. We shouldn't depopulate categories out of process. If one believes that a category or categories is pointless, it should be taken to CFD. At a glance it appears that Category:Establishments by country is somewhat established, so to depopulate in the way as has been done thus far isn't the way to go about it. Take the above linked category to CFD and gain wider community input on the issue, particularly as some hold one opinion and others hold another. Try it that way instead yeah?  I'm chanting as we speak
