I think that wildly overstates the influence these companies have. Amazon is trivial to avoid. Just don't shop there or at Whole Foods. Facebook is a bit trickier because you might be forced there by a social group and they have a huge web of trackers.

Google is really the issue. They are dominant in search, browser, and maps, and they're half the mobile duopoly. It's very difficult to avoid using their products entirely and even if you did, their dominance allows them to dictate how the internet works, to a certain extent.

Avoiding Amazon would also mean avoiding all aws services, not letting your data hit their infrastructure.

Not a huge disagreement here, but I think Facebook is completely trivial to avoid, while Amazon is much less so.

I couldn't care less about Facebook. Yet, while I certainly could live without Amazon (or Whole Foods), their service is very nice and WF has things I can't buy at other grocery stores around me.

Good luck avoiding having your data collected by facebook via third parties, and good luck avoiding the effects it has on the society you live in.

Also they've been hoovering up all the talent available they can get with fat salaries and stock grants.
