More often than not though, in the past, companies have complied with the Kremlin's requests to remove content it's deemed subversive. Earlier this year, when Twitter and Google refused to respect similar requests from the Turkish government, it led to a showdown that saw the services blocked completely in the country. It's possible, though unlikely, that the Russian government could use similar tactics to keep its citizens from getting information about the rally. But, at this point it would appear the cat is out of the bag and blocking the services wouldn't probably only draw more attention to the protest.

This is just the latest in a series of events that have seen tensions between the western tech companies and the Russian government on the rise. Google recently closed its Russian offices, and the government is trying to force the companies to store user date on servers inside its borders. At the same time, relations between the US government and the Kremlin have grown increasingly strained over a variety of issues, including the military showdown in Ukraine.
