Yes, which means that the raid and confiscation of computers, etc, isn't really about copyright enforcement but about grabbing data, making data unavailable for use, or otherwise as the article suggests causing general hindrance. Verifying the legitimacy of Microsoft software, as far as I'm aware, is a fairly trivial matter of checking serial numbers, so this isn't something which would require computers to be seized for significant periods of time, or necessarily even moved from their desks.
That Microsoft declined to facilitate the checking of serial numbers after claims of piracy is reprehensible, and all the more reason not to use their software in the first place.
