Break it up?
Like how the fedgov broke up the Bell System?
No.
That will just mean there will be a dozen different sociopathic Rodent organizations all stealing and selling our personal information for profit while censoring anti-Rodent content.
What should be done is simple:
Ban the sale of private information by private companies, REQUIRE companies that collect such information to become both civilly liable for the illegal sale of private information, and require that any release of such information to government agencies but pursuant to properly written subpoena or search warrant.
Ban any operation that links personal internet searches and purchases to advertisers. I searched for a replacement pool pump last week using my cell phone. Now this browser on my PC is calling forth all sorts of advertisements from Leslie's Pool Supplies. Must be just a coincidence.
Anyway, the TELEPHONE companies are not allowed to divulge our names, addresses and phone numbers to other commercial or private parties. Time to place the other communications companies under similar restrictions, no matter how large or small they might be.
But I am 100% certain that we will see laws forbidding elected Congressmen from getting rich on the stock market while in office before we see laws with real teeth against Fakebook and Twitter and Google/You-Tube.
