This is true in a practical sense for most laypeople, but it's not literally true and doesn't have to be.

(1) Don't buy "smart" devices that collect data. You don't need them.

(2) Don't visit facebook.

(3) Don't allow your browser to run javascript from facebook or anyone you don't trust.

It's that easy, and there are tools to help you do (3) such as adblockers and other browser plugins. For (2), even if you occasionally visit facebook, you can minimize information collected by controlling the environment you visit from (e.g. tor browser, VPN, virtual machine, etc).

The more challenging problem is data that your friends give Facebook about you, such as your contact info and tagging your face in photos. I wonder how long under GDPR till someone sues their facebook friends for providing information without permission?
