"adtech" implies targeting and/or personalization, otherwise it wouldn't have the "tech" part - just "advertising".

Whenever I've heard it used it's referring to general ads infra, which includes personalization. But there's also a lot more to it

[Bakary]

If you provide infrastructure or support for something, and that something is almost exclusively surveillance and data-gathering based, that's not so great either.
