Janne, you seem to be missing the social movement part of the Free Software social movement.
Solidarity is not just take care of stuff that harms you, and screw the rest.
Sure, if you have those bits in your disk and they don't take away any of your freedom because they are inoperant on your computer, you lose nothing in practice.
But when you tell your neighbor to use the same software you use, it might very well be that your neighbor would find herself deprived of control over her different computer, because of the very software that you dismissed as inoperant.
Solidarity suggests us to stand together against this threat.
Besides, if the software is useless for you, harmful for your neighbor, potentially harmful for everyone else, and the attitude of the proponents of such software is harmful to everyone, the question that really matters is not why take it out, but rather why put it in in the first place. Why give anyone the impression that it, and the hardware that only works by taking your freedom away, are something to be wished for, rather than avoided?
