For its part, Microsoft maintains that it doesn't work with "any government" on surveillance, or conduct any espionage itself. Its soon-to-be-acquired job site, LinkedIn, is currently fighting a Russian attempt to block access.

The NBC source doesn't say when (or if) this transition would happen, or say whether other American companies are on notice. Russia has more than a few incentives to kick Windows and Office to the curb, though. National pride is the most conspicuous reason, as domestic software could both foster the local economy and spite the US. However, it's also a matter of control. If Russia makes the software, its government has more power to control that software -- officials would have an easier time blocking content and inserting surveillance tools. While this could reduce the chances of US agencies snooping on Russian activity or launching counterattacks, it would primarily be helpful for quashing political dissent.
