AdTech gets a lot of flak, but I did spend quite a lot of time in my career building tools on the opposite side of this. We also did reverse engineer what the big networks like Google were doing but with the objective of learning the best techniques to use – which is actually quite disappointing in practice, these days the most important measure of being a real user is whether Google can doxx you or not. It was quite fun for a while, and some of the tools and techniques ended up having applications beyond ads, for example developing 0-day techniques to unmask Tor and VPN users (webRTC leaks, etc.) that could then be reused on seized/honeypot onion sites to catch predators.
