This won't mean a darn thing to Microsoft. Come on now; they'll pay off i4i, pass the costs onto consumers, and go on selling Word like nothing happened. Sure, it's all a bad joke, but that's how the game works, and these people are professional gamers.
I4i didn't bother going after anything open source like Open Office, or web developers, or anyone else, because there's no vast hoard there to loot. For that reason alone, this whole thing should be tossed, but that would leave money on the table, and parasites don't like that. They'll gleefully make big bad Microsoft pay, then they'll moan when they see the price of Office went up again for the next release.
