Getting involved in only narrowly technical issues won't do.
What if your boss asks you to build a database to help the government track Muslims/illegal immigrants etc and you're uncomfortable with that?
If you supported the FSF, that might improve your chances of being able to build the database using free software.
Whereas if you unionized, that might improve your chances of being able to refuse to build the database in the first place.
And what if you're uncomfortable with much of the revenue you generate for your company going to the idle shareholders rather than your fellow workers?
Unionizing can help there too. Imagine if software companies were owned by workers themselves. That could be a reality if more of us unionized.
