I'm of the view that the best we can do is restrict the information available to these companies, and only to the extent we can control it directly, and only to the extent that one can tolerate various disadvantages in so doing. For example I don't upload images of any photos I take from my smartphone and I don't use social networks at all. However my spouse does, my friends do, and they all refer to me and pictures of me they've taken and there is nothing I can do to stop it. I can ask them to not do that and to minimize it if they must do it anyway but that's the extent of my control as far as that goes. I could be completely disconnected from the internet, but my view is the disadvantages there, due to the aggregate mass populace's use of it, are too much for me to tolerate. So I use a popular browser and engage in various online activities.
