There's no magic necessary. TFA highlights the exact mechanism by which markets can fill a gap or need via entrepreneurship when incumbents fail to deliver what customers want. It's not guaranteed to happen or work in every case, but there's money to be made by giving people what they actually want.
It would be nice if this could happen more smoothly and rapidly, without some random people having to become experts in tractors from the ground up, and that's what regulations could help with. Say, if it was legal to copy from the best.
But the company in the article isn't filling the gap. Farm owners want the technology. They don't want to be held hostage over the technology when it needs maintenance, repair, or adaptation after the initial sale.
A lot of electronics is useful, it can reduce fuel use or help with more accurate driving.
Farmers are just pissed they lose the ability to repair the vehicle easily or get stuck with monthly subscription because tractor company has changed the terms and you are praying they don't change it further.
