Internet brings a way to share information about service/product/review quality. But it deliver also tools for censorship. People will comment/complain about the problem on page controlled by company making product, so company could do not publish people opinions. There exist service such like wykop.pl, but nobody uses it. First place, where people will leave comment are place controlled by vendor good this describe.
We need new portal or integrate existing into browser, so comment would not be deleted because it is bad for company. Of course, somebody should decide, which comment to publish, because they can exist comments breaking law.
