My initial draft of this thread did have a question about flag-day activations, but since there were already so many questions posed, I didn't want to have too much stuff in there.  But since you raised the point about 148/UASF, I suppose we'll add it into the mix.

For the record, I wasn't a fan of UASF either.  But with the way it was coded, with an arbitrary date to activate, it's not something that you can really preempt.  It's just a case of waiting to see who does or doesn't run it.  Do people feel this is a somewhat reckless approach to consensus?  Or is it again something that boils down to freedom?  There's currently no way to prevent someone from coding something with an activation date.  And, personally, I don't think that I could ever be convinced that it was right to prevent someone from doing it, even if it were possible.  Even if I don't agree with the code, it's not my place to tell someone they can't/shouldn't make it. 

I'm glad that's not the route we took, but if something similar happened again, I'd still defend their right to do it, even if I was simultaneously saying it was a terrible idea.
