The article is about "a big California farmers’ lobbying group" signing away rights on behalf of its members to John Deere. No government is blocking the right to repair, some companies are. Others aren't, but purchasers don't prioritize their products.

There is no law in the United States that blocks or restricts rights to repair.

The fact that it was possible is the problem. EU consumer laws make such agreements void. But I guess it’s a matter of mindset. Maybe that’s why I’m downvoted below zero :P
