We, as a niche portal, serve a narrow market, the community of people interested in alternatives to western mainstream culture. It would be unrealistic to make it illegal to focus on a narrow market due to potential laws that restrict restrictions. Every portal can't be forced to be everything to everybody. Better than pressuring government to make laws that prohibit private censorship, I believe the better action is to directly act against individual corporations that are heading down the censorship road by creating negative publicity for them. If their revenues drop, they will change their tune.
Corporations are much more sensitive to negative publicity than governments are.
Even a small number of very vocal activists can change the course of corporations. I am giving the portal that wrote me the letter mentioned above a chance to rethink their recent policy change before I publish their name and start a campaign against them. I responded to their letter in much the same tone as this article. If they realize the error of their ways then no harm is done. I also believe the chances of this happening are near zero.
