These days activism is more like: think what I tell you or else you are evil and unworthy of participation in society. So yeah, people are kind of tired of it. It's basically like participating in Soviet-era public ceremonies or regurgitating official party lines. Not that that's what's going on with the "GNU/Linux" controversy, but it's the general phenomenon.

Also, there's an older, I think better, sensibility around still: that controversies should be left to those directly involved with them. Let the distribution maintainers, the FSF, and Linux Foundation sort this out amongst themselves. It's really not my place to be involved in this decision anyway. Not that I don't love sharing my unsolicited two cents online, but some people don't even like that.
