Yep. And we thought oppressive censorship only existed in totalitarian states...
In the past, the state was the only entity that could, in most cases, control publishing, access to markets, etc. Now with consolidation of Internet sites, some of them
are the market (Amazon, eBay, etc.),
are the press. And if someone doesn't like you, they'll get you kicked off them. The former protections should be extended into these domains ... but nobody seems to want to do this.
