You don't owe random strangers your time, and it's so strange to me that people feel so entitled to other peoples time. Can also be argued that it's rude to engage a person on a topic they're not interested in.
I do, to an extent, agree. But I also think it's impolite to have relationships where "we're going to talk about what I want to talk about, but when we go to talk about what you want to talk about I'm just going to pick up my laptop and ignore you or tell you I don't want to".
You could argue, in your description, the same about RMS - he might feel entitled to someone's time to talk about free software.
