When it comes to adtech, I don't immediately think of Big Tech, but they are in fact the largest aggregators of data which feeds into the system. I always wondered why there isn't enough government pushback or regulation to limit this. I guess this post is maybe part of the reason.

I think in the public sphere, many don't think of Big Tech as privacy intruders, even with Facebook's public failures, many continue to use their services. I'm not sure if most people care or don't care. But when Apple took the initiative to limit 3rd party cookies by asking it's users directly whether they wanted to allow it or not, the majority chose not to allow it. Which shows people don't want their data to be tracked.

On a related note, I don't think I've ever clicked on a banner ad on a site, or any twitter/youtube ad, etc. There's certainly an element of marketing that's brand awareness. But all the other metrics about click rates, and purchase intent, etc- I have no idea how this all adds up to the massive numbers that Big tech pulls in from ads on the Internet.
