Licensing monopolies?

Important suggestion was added to my discussion on Wikipedia:

"There's a very simple solution. If Nikolay wrote the text and posted it on his own website, then all he has to do is to post, on the same page, a statement that the page is released under GFDL. Right? Shouldn't this be a standard answer for people wanting to re-post their own work here? Cphoenix 00:27, 15 January 2007 (UTC)"

Does it mean that the web is being monopolized by the major licensing projects (GPL, GFDL, Open Source, Creative Commons)?

Is there any independent consideration of their quality and impact, if it is a question of standards?

What law system (of which country) will dominate (or already dominates) in the web which isn't controlled by a country or by their group (or is being controlled)?

How all this must be?
