What if you criticize Amazon? Should you be banned from using all their services? What if you criticize private enterprise in general? Banned from everything except services provided by the state then? Your interpersonal examples where both people/groups have very little and similar amounts of power. 'Consequences' to speech become dangerous when corporations or even larger groups of people get involved.
You have somehow made a logical equivalence of some benign speech like "criticize private enterprise in general" and then projected that on "every company in the world bans you".
(1) There is always some company willing to sell a product/service for the right price. Even to genocidal maniacs, and especially to everyone who is more socially acceptable.
(2) Every competing company smaller than Amazon wants to steal Amazon's business. If you are banned by the big company, they are likely to want your business. They may use their compassion and willingness to be criticized / reverence for "unlimited freedom of speech" as a competitive advantage.
(3) Every "undesirable" company eventually finds suitable replacements for their vendors. DailyStormer, Parler, 8Chan, InfoWars. They are all still on the internet.
There are legitimate concerns when there is a monopoly / small oligopoly in an industry with no substitutes. And there are legal concerns when governments sanction people/organizations without due process. But your comment wasn't useful to any informed discussion of these topics.
