It is either a Free Speech issue or an Anti Trust issue with regards to consequences, I lean heavily to Anti Trust because they have Violated it in Spades.
Yes! Especially in the case of Apple, Google, there are definite anti trust issues. When one company controls so many facets of commerce and communication, they have become like the government.
So for example Alex Jones... they shut down his FB, YouTube, Twitter. Have they shut down his PayPal? I think so. What about if banks, taking their lead from the big 3, also decline to do business with him. Its only a matter of time before the web hosting company declines to do business with him as well, next Microsoft says he has violated their terms of service, so no Microsoft applications, etc. Perhaps gmail will brand any incoming email from his organization as spam or hate speech and blocks it. Chrome blocks his site or decides its not secure. He is unable to do business.
Instead of Alex jones, insert Free Republic, the NRA, a Pepper Spray manufacturer, Marijuana dispensary, Pro Life activists or any other business or person that is deemed controversial.
These are sticky issues, when a company is so large and has such a monopoly, that it can reach across into almost every aspect of a business or persons life.... I sure dont know what the answers are. I hope the Supreme Court thinks through all these issues.
