well, to me data brokers exist only because it’s possible to profit from it, and in the end, no legislation will totally ban that practice. The issue is apps developers trying to monetize through users data, and the monetizing model found is not going anywhere, popularized by big companies, and now followed pretty much by anyone wanting to monetize. Users really need to become aware of the issue in the 1st place, and not just few, I mean, like 80% or so of them, and to start with, stop using OS that share their data underneath, and as most of it is proprietary, that means getting rid of android, ios, ms, etc, and use at least open source OS, but preferable FLOSS ones. Then start picking privacy respecting apps, and as much FLOSS as possible. And if a good chunk of user become aware, and start changing their habits and consumption culture, then that monetizing model will be really impacted. No legislation will cover all corner cases, to get rid of the bad practices, there will always be front/back doors found. It’s culture and consumption which needs changing. And as with anything worth, it’s the hardest to get, :(
