If the worker has a "choice" between a familiar application with guaranteed compatibility, there's a slim chance a switch is going to take place. It requires standardizing document exchange on open format types (instead of continued use of Microsoft's proprietary ones) and familiarization to the substituting software suite. This doesn't mean these applications and formats should be dropped entirely (at least not short-term), but that FOSS applications and open standards should be defaulted to. Otherwise this should be regarded as gesture politics.
