I've provided several written and oral testimony on behalf of "Right To Repair" Laws in several states. What prepares me for the discussion is over 3 decades of interest in Warranty Law, Planned Obsolescence, Trademark and Patent Law.
Here's the thing. Most of the testimony in favor of Right To Repair is based on past Planned Obsolescence techniques. Most of the testimony AGAINST Right to Repair is based on scary things that might occur in the future, if OEMs are forced to stop blocking independents (who according to OEM TV ads are far more likely to stalk you than OEM repair shops).
But the VERY SCARY future is based on what Planned Obsolescence has in mind.
