Is putting barriers into how huge multinational companies can exploit their data farming to cement an unchallengeable position in the market and kill off competition or dissent within the system "tight control into who can put messages in front of the general public"?

You are framing this as if I am somehow advocating censorship towards people, yet I am advocating the opposite position. Executives shouldn't be given a such huge powers of data mining and information distribution and ability shut powerless opposition and competition out. This is about preserving equal voice to all people, and preventing juggernauts from squashing it.
