One problem with 'right to repair' is to define exactly where to 'draw the line'.
Say your tractor fails..diagnosis determines it's really a defective part on the daughter board on the main computer board. R2R would say YOU have the right to unsolder the bad part, replace it ? I can count on one hand the number of ETs that CAN do that repair, one reason why 'board swapping' is common.
Say you like a certain tire on your tractor, but the 'computer' has been calculated for THEIR tires, so 'apply rates' are wrong(just a wee bit)..just HOW can you change that? That kind of data is hardcoded into the CPU,think any court will allow you to change JD machine code ?
JD has 25%+- of the World market, so they have a HUGE interest in keeping R2R stalled....they also have a monsterous bank account.....
I've seen MFRs design and use very 'custom' parts ONLY available from them, so when you need that part, you have to pay them their 'ransom' money. What should be a $1 bolt , is $39.99 plus taxes.....
