Brave offers the most privacy friendly browsing available by default on both desktop and mobile.

This easily negates much of the privacy invasion efforts of ad networks. Even if they do continue to track you, this hinders their ability to put "personalized" ads in front of you.

This won't stop advertising but it will force the industry to adopt more sensible, privacy respecting "context sensitive" techniques.

Social media apps are a different story.
