As to using someone else's tracker (tracking is what those devices do most of the time, so why not acknowledge that's what they chiefly are by calling them by their rightful name?): this is right in line with understanding that software freedom concerns control of one's own computer. Remote services (such as /., Hacker News, Google mail, and more) might run on nonfree software. That's a bad choice for the computer owner (all computer owners deserve software freedom) but it doesn't say much about use of the service because service users don't have a say about someone else's computer. By the same token, those that choose to own and keep trackers on their person have already divulged the location of the tracker (and thus themselves), and that choice was never Stallman's to make. So the choice for Stallman (or someone using someone else's tracker) comes down to making the call or not.
yep, except when you spend 2 hours in a conference explaining why people should use free software. At that point, as a service user, RMS says something about someone else's computer.
I agree with the logic of your argument, but it sounds like a lawyer's argument : it's ok by the law eventhough i'ts not super "ethical".
Be reassured, I support free software, specifically on the political side.
As to "spend[ing] 2 hours in a conference explaining why people should use free software": Be careful about the trap of concision as explained by Herman and Chomsky in "Manufacturing Consent". It takes time to lay out new ideas, ideas which mainstream media never discuss. Software freedom is still (even 30+ years after the fact) regarded as a new idea.
Regarding saying something about someone else's computer: I don't clearly understand your point. Are you sure this isn't giving someone convincing reasons to favor free software? Can you point to an example of where RMS is a service user and makes demands of that service beyond recommending what they ought to do to get the software freedom they deserve?
"I agree with the logic of your argument, but it sounds like a lawyer's argument : it's ok by the law eventhough i'ts not super "ethical"."
What's not ethical about not having control over someone else's computer?
let's just say that what you say is logical but sounds a bit incoherent to me. I expect coherency at the level of one's choice : if I complain about a tool because it's non free, because it's spying, then I do my best to not use it, be it mine or someone else's.
RMS says : "proprietary software represents an unacceptable danger to a free society" (citation from https://www.fsf.org/about/what-is-free-software ), but somehow proprietary software is acceptable when one needs to make a phone call...
I'm not trying to nitpick about what RMS says ('cos I totally agree with him, and I perfectly understand what the whole thing is about), it's just that, on that occasion, I found the argument weak.
I'll stop the argument here 'cos my english is not good enough to convey my idea precisely (and it's late) :-(
