Of course I've never operated under the illusion that Six Apart cares about LJ users - they care about profit like all good capitalists, nothing else.

I'm not attached to LJ in particular, but to fandom, but overall, I'm more in favour of fighting such challenges on LJ rather than mass exodus - because those things are bound to be happening again, and showing strength is always a better option than encouraging more of the same by evading conflict. Though really, it depends - if it keeps happening, it might be worthwhile to consider moving...
