Some are to a degree. There was a lot of suggestions by Mercedes enthusiasts a few years back telling Mercedes that this needed to be done for older vehicles to be able to keep them running. I think they listened to some degree - but not sure what happened after that.
With GM vehicles I notice that there has been forums like
https://www.pcmhacking.net/forums/index.php where people have got into the older computers and understand them quite well.
The main problem is that it just takes perhaps a decade for the systems to reach the 'Open Source' level via reverse-engineering and by then everything else including shiny paint on your vehicle has moved on.
