It's been reported many times that Facebook creates shadow profiles for everyone who does not use FB, and still tracks them across the web. So avoiding them is harder than "just dont use his products"

But you can at least avoid having your own camera/mic turned on all the time if you're not using the app.

If you don't like what John Wayne Gacy does to kids, don't hire Patches the Clown for your kid's birthday party.

Hyperbolic, but simply boycotting the products isn't enough here.
