> Their profits come from selling your data to others
It is a common misconception that FB and Google sell user data.
E.g. see https://www.facebook.com/help/152637448140583
"Google has also played a leadership role in creating industry standards for transparency and data protection. More than a dozen privacy employees at Google spoke to WIRED about how they make sense of the paradox of their work, insisting that there’s no internal pressure to compromise privacy protections to make a larger profit." -Wired (https://www.wired.com/story/wired-guide-personal-data-collec...)
Google also sells a plethora of physical products (Pixel devices, Nest devices, etc.) and services (Storage[Drive], YouTube premium, Stadia, Nest, Fibit, etc.).
This would be similar to calling Amazon "just a [book]store or a marketplace", whereas they also have their hands in Cloud Computing, logistics, grocery, iot, etc.
