I'm not sure... I think I'd be more comfortable working for a weapons shop than for (tracking) adtech. Ethics is a spectrum, so there can be many opinions on the topic.

Going back to adtech, I more or less equate it to the tech you alluded to, as well as global tracking, NSA-sized surveillance, and a complete disregard for "privacy", regulations and civility. Would any self-respecting person follow their neighbors around, write their every moves on a notebook, and sell that to the highest bidder? It's literally what is being done by those tracking giants, on a much bigger scale (and Google does track your every move, or does its best to do so).

I feel like I'm distancing myself more and more from conventional Internet platforms as a result.
