Earlier today I wrote a post that explained why it I think it would be a bad idea for the government to be involved with mandating who private social media platforms must be allowed to use their services, but I do agree that major media companies should be fair with their practices anyway.
I think it should be made in the best interest of such companies to be fair to their users without needing the government to be involved in that process. For example, new companies who are in fact fair to their users could arise as competition that would soon become popular in place of the companies who discriminate.
I think it is mostly a matter of activists keeping track of the companies who are unfair to their users and making sure that people are aware of those companies, and it is also important for alternative companies to be promoted.
This video explains problems with the major internet content providers such as Google..
I think it is mostly a matter of people being made more aware of issues with the problem companies and informing them of effective alternatives. For example, other search engines than Google exist that don’t track users, such as “DuckDuckGo.com.”
