I might be too much of an optimist, but I feel the ISPs (barring Reliance) have rolled back the ban due to the bad feedback from the users, specially on the social networking sphere which has a multiplier effect. When I protested to Airtel_Presence on twitter yesterday morning, I was told they are looking into the matter and will resolve it soon. Had everybody taken it in their stride, the ISPs would have been only too glad to continue with this ban even after the movie in the guise of this court order and thus saving on their bandwidth and upgradation costs. Learning from this, the next time they do anything like this we should be even more strident in our protest.
Also, taking this to the next step we should use the social networking spaces of movie concerned and the people (the stars and other prominent people) involved with the movie telling them that this is not acceptable to us. I am sure it will have a positive effect.
