It's not only about tractors. Cars and other equipment are based more and more on computers too. I saw 60+ year old tractors and cars, all work fine. For expensive physical products, I would rather choose one with a high quality and a long lifespan with no computer in it at all. There are only a few left like Mercedes-Benz G-Class, Land Rover Defender, Hummer H1, Jeep Wrangler, Caterham 7. http://en.wikipedia.org/wiki/Mercedes-Benz_G-Class http://en.wikipedia.org/wiki/Mercedes-Benz_G-Class , http://en.wikipedia.org/wiki/Land_Rover_Defender http://en.wikipedia.org/wiki/Land_Rover_Defender , http://en.wikipedia.org/wiki/Hummer_H1 http://en.wikipedia.org/wiki/Hummer_H1 , http://en.wikipedia.org/wiki/Jeep_Wrangler http://en.wikipedia.org/wiki/Jeep_Wrangler , http://en.wikipedia.org/wiki/Caterham_7 http://en.wikipedia.org/wiki/Caterham_7 . Watching the Top Gear Specials where they drive with old cars through foreign countries on crappy roads - I always think about how would a modern car survive that - it wouldn't. For example the Porsche 924 (1980s) was cars with a lots of computer chips, it was completely dead (the dashboard lighted like a Christmas tree, the windscreen wipers was the only thing working) after a few days driving through Africa. Richard Stallman was right. The GNU (L)GPL 2+ is a very good choice for open source projects - at least for bigger (for smaller BSD/MIT is good too).
