JD is more a problem than a solution, let me explain: their machines run on closed code, like the proprietary UNIX of the 1980s/1990s/2000s, like Microsoft Windows and all flavors of MacOs XI. Apple. It's an old way of thinking about 'software economics'. If GNU/Linux killed the competition in the server environment, it wasn't because it was free, but because it was open code and the community.

The private code blocks the economy. IF JD die, what will become of their customers? they will not be able to maintain their machines, it would be added one crisis to another. As I have said elsewhere , there is nothing to say that a Linus Torvald equivalent , for farmers , is not hacking one of these machines , for an open source equivalence
