There will be even more free content in the future - there is only 1 way to stop it... politics/goverments, but thats probably not going to happen within the near future...
However I think its a matter of who controls the free content, not that its there. If people who control the free content is doing it to make big $, then it will be good for all
If it will be people who gets more excited when their counter rank rise, then when they receive an extra digit on their paycheck - well then it will not be pretty in the long run.
I wish that every paysite owner and every tgp owner could switch roles for just 1 day... then paysite owners would see how much free content matters, when getting traffic/bookmarks, and tgp owners would see the costs of having a paysite.... they might end up understanding eachother, and finding ways where they both will benefit
