The shiny side of the foil needs to be on the outside of the hat. The problem here isn't government intervention, rather a lack of same. The problem is corporate sociopathy and lack of standards. The standards should have been set up before anybody started building equipment. Where government fell down was not mandating that. Not a surfeit of regulations but a lack of them.
And had there been a monopoly there would have been no compatibility problems, but would have caused worse problems.
