I'd contend that it absolutely is. Adtech is creepy and invasive and weird. Flock is going a step further and actively tracking our movement through the cities where we live.
I don't like either of those activities, but I think one of them is much worse.
One is making implicit assumptions based on data available to it. The other is literally saying "hey they're right here at this time". At least adtech has _some_ level of obfuscation to it.
But I'm with you both suck.
