In a comment on this topic I asked a similar question.
An argument that RMS will likely use, is that if you use proprietary software, you are helping to keep the majority of software proprietary, while if you use and advocate Free Software, you will help in improving it, which leads to a better medium-term situation.
The same argument can be used for situations where a vendor benefits from the network effect to keep people locked into their service. These arguments can be made for using the metric system in the USA or for resisting the Mafia in Sicily; in many cases it is hard to get everyone to behave in a way that leads to optimal situation.
