In the automobile industry the car manufacturers tried to do the same that cartel lift companys are doing still.

They tried to have this repair information as their own information and to be used only in their own car workshops. They were claiming that the quarentee of car would be only valid if the car owner uses only car manufacturers "own" service and repairs. After a short while this was banned by law.

The new law allowed small workshops to buy tools and information for a reasonable price. Manufacturers of car´s have to give this information to anybody.

For me it hard to understand why is this any different in elevator business?
I JUST DON´T GET IT !
