Intellectual property is, after all, a right granted to producers, but it is a right that they must not abuse in an anti-competitive way. In a number of countries, particularly in the United Kingdom, where this movement started, it was quite clear to the Monopolies Commission at the time that the car manufacturers were abusing that monopoly, and that is why it was removed.
In zahlreichen Ländern, insbesondere im Vereinigten Königreich, wo diese Entwicklung ihren Lauf nahm, lag es für die Monopolkommission damals auf der Hand, dass die Autohersteller dieses Monopol missbrauchten, und es wurde daher gestrichen.
