I'm not sure what you're saying. I've (sadly) worked with and met many adtech professionals over the years and they are just not the kind of people who would go in for more privacy.
adtech is a big area. It's not clear who you're talking about. People who sell ads? People who buy ads? People who make the networks?
AIUI, web sites that host ads probably want the ads to be shown so they can get their money. And people who buy ad space probably want the ads to be shown so they can market their product or service. And maybe the ads will be shown if users white list ad networks that respect privacy.
