Regulation is the solution to this prisoner’s dilemma.
Good regulation: right to repair, manufacturers must supply manuals.
Bad regulation: JD bribed senators to write regulations that make it insurmountably difficult for new players to enter.
Calling regulation bad because corruption is baked into the US Constitution makes it really hard to get anything done.
Every regulation looks good or at least defensible in abstract, especially when some peddler is trying to sell it and the consequences aren't obvious yet.
