To what end? "illegally undermine competition?" She is inferring that Google/Amazon/Facebook are committing anti-trust crimes? What proof does she have? >Companies would be barred from transferring or sharing users’ data with third parties. That can be done without breaking them up. I don't think she realizes that splitting up amazon and amazon basics will do little to nothing. There are other things that can be done…
Amazon is not a Standard Oil by any measure as they have ample competition when it comes to online sales. Facebook is still an opt in environment. If you don't want to join facebook you don't have to and no retailer is dumb enough (well that might not be true but I haven't found one) to require you to be a facebook member to purchase products or services. Google is, well google. I don't have to use their search engine if I don't want to.
