End of the World with free services for everyone?

Some changes that might be slightly less dramatic than ones read from the Mayan calendar, but still have a bit of "tipping point" feel to them:

Costs of the online services are becoming more and more real, the "advertising only" revenue model probably doesn't scale at the same pace as the costs and - perhaps more importantly - online payment systems have made it convenient enough to pay for digital content and services. Once you make the leap and enter the "online store world", it is actually easier to pay the virtual busker online than the real one in front of you!
