Q1) No, it is not too early. Recently with the boom in the smartphone market everybody is using a huge number of internet based apps on a daily basis. This means there are going to be an increasing number of app based start ups. If service providers are given control then already established businesses can easily establish monopolies in the market. This will lead to decreased economic output.
Q2) No. As we have seen communication plays a huge part in our day to day lives. For years TSP's have overcharged us for using sms. Internet based apps are almost free as they give us unlimited usage and services for a fractional cost. This is as good as hidden charges. If it costs them less then they should not be charging us for using their services. It's not ethical for them to charge us here.
Q3) Yes. Now that OTT's are able to provide the same functionality for an exponentially reduced cost TSP's have reduced earnings.
