I think it's really just because it was successfully made into a mainstream political issue. So now you have to appeal to the mass audience, not just IT nerds; and we're just seeing the same tactics that is routinely used to whip up support (or opposition) to other stuff.
I'm actually weirdly uncomfortable about this. It's like being the guy who has cried wolf for many years, and now half of the village is there with you; but you see them pointing at rocks, logs etc, and insisting that these are all wolves, and we're all going to die now. It really made me question just how many people who happen to share my political positions, do so because they genuinely understand and agree with the policies, and not because it's just what you're supposed to do when you have a certain identity (liberal etc).
