Microsoft are still doing it. The company that I work for didn't just pay for Office subscriptions because we wanted Office for Mac (and I didn't want to get it on subscription either, but the pricing strategy is designed to penalize you if you don't). We actually have access to three different Office-like products already (iWork, LibreOffice, Google Apps). None of them can yet 100% support Microsoft's "standard" file formats.
