For example, we've put severe restrictions on what kind of strings employers are permitted to attach. We also look very carefully at concentration of capital and collusion.

Note that this is not necessarily a call for legislation, but certainly people should be aware of who shapes and filters their communications, and how, just as they should be aware that e.g. 90% of US media are owned by 6 companies (in 2011, down from 50 in 1983) [1].

There are entire university departments dedicated to analyzing the influence and cross-ownership of media and capital, even though one could just as easily dismiss that with "What is there to look at? It's just free markets at work."
