Abine & TACO
I don't understand the bloatware claims about Abine's software. I've been using it for a long time, and sure, it has its bugs from time to time, but it's a great utility overall.
And I echo everyone here who's saying that ALL tracking should be opt-in. It completely violates everyone's privacy and expectations to impose it on us. We can't get to the point where we EXPECT these sorts of invasions, because the Fourth Amendment's protections depend heavily on the public's subjective expectations of privacy (in addition to the objective "reasonableness" standard of whether that expectation is valid).
