The current delay between the availability of essentially telephoning, particularly on mobile phones reminds of the absurd protectionist tactics used by the dairy industry in the 1930s and 1940s. In order to have yellow oleomargarine, you had to use a packet of yellow dye and knead it into the product.
The contention by industry spokespersons was that if they allowed yellow margarine from its maker, there would be some arcane health issue. They would never admit that they were obstructing yellow margarine because its price would nearly wreck their business.
Now the "carriers" are clinging for dear life to the absurdly expensive phone calls and putting obstacles to VOIP wherever possible. We all know that the same "networks" that send all this stuff around are used for all communications traffic and that the phone companies are as doomed as were the butterlords.
Meanwhile, we go through this silly phase of disinformation ("VOIP doesn't sound as good") and pretension. Could we please get over all this and get on with using OUR networks however we want?
