First they try to make HTTP impossible to use (nag pop up) to limit the websites, then they try to introduce pay-per-view model and subscription model.
Welcome back to the pre-1999 AOL/MicrosoftNetwork/Compuserve/BTX/Minitel/etc - closed networks where pay-per-page-view was prevailing - then the free open WWW won, supported by advertising.
The good thing, it only takes other websites that provide the same or comparable content for free.
If micropayments were ever to really take off, it would shift the balance of power on the internet in an interesting way.
