Jailing political opponents for Microsoft?

According to Marina Litvinovich at LiveJournal (the link is to a version translated by Google) Russian police came into the home of Boris Batyi in Rostov-on-Don and arrested him for having an unlicensed version of Windows. (The portrait, according to the note, is of Marina.)

Police seized his computer, which contained documents belonging to OGF, an opposition party headed by former chess champion Garry Kasparov. They then went off to seize the computer of the man's wife.

This may have nothing to do with open source. Pirating Windows may have just been an excuse to harass regime opponents, and if they didn't have that perhaps they could have used something else. Although it seems one tendency of the Putin regime is always to color oppression with the appearance that the rule of law is being upheld.

For instance, as one user noted, they might have nailed Batyi for using a cryptographic key that was not licensed by the state. They might have located a song and charged him with violating its copyright. They could have used any excuse, or none at all.

So is this just a set-up by the Russian government aimed at Microsoft, or should leaders of anti-government movements around the world make sure they run nothing but open source?
