I do think that any attempt to provide access which is limited & curated should be shouted down , because it is totally disastrous in the long term. There are other business models which are currently in play , which can be considered, such as

- Aircel has free access at a speed of 64kbps (very slow) but still the user has access to the entirety of the internet , not a walled garden.

- There is a different model, where user view an ad on a per day basis and get a certain data limit in return. Mozilla has implemented this. This gives access to entirety of the internet.
