No. False thinking. When it's a billion users big, it is no longer the sole property of anyone, it is a defacto public resource.
Anything that is used by millions of people to communicate with other members of the public is a public resource, and must be regarded as a public resource, regardless of how it was began and who created it.
And again, on that I agree with you. Bust them up. Failure to trust bust Silicon Valley was a major fail for the Trump administration as it would have done the country a great service.
