Small automobile repair shops in Massachusetts have banded together to have the Bay State legislature create a bill that would force large automobile makers to provide all the repair diagnostic tools and software they provide their own dealers. This so-called "right to repair" law represents another lurch to the left, and it is unsurprising that it comes from the People's Democratic Republic of Massachusetts.
The diagnostics and repair tools furnished to dealer repair shops are proprietary and as such, should be protected by the law. Engineers and designers put their intellectual capital to work on those systems--funded by the automobile manufacturers seeking competitive advantages. This shouldn't surprise anyone--this is capitalism.
Forcing the large auto manufacturers to "share" their proprietary information with Mom and Pop's garage may play well in the utopia that is the Modern Planned State--but in the real world, it is yet another instance of "spreading the wealth around" by handing to these garages advantages they invested nothing in.
