I think this is an oversimplification at best. Right-to-repair has huge support amongst e.g. farmers, who are not homogeneously left-leaning by any stretch.
"He was initially completely against any restrictions by companies on farmers from repairing their equipment (which might have resulted in voiding the equipment's warranty). However, Rossmann later admitted that his opinions were not completely correct due to a lack of expertise in farming machinery; this came after he received mail from a John Deere employee stating how allowing farmers to tune their tractors can result in harm to themselves and possible violation of environmental laws.[14] "
This seems to confirm my point...
From what I can tell, the only relevant bit in that video is that he concedes he didn't know that tractor racing (tractor pulls) was a thing.
And thinking any environmental regulations should exist certainly doesn't place you on the left. Do you think Richard Nixon was a leftist?
Rossman spends about the same amount of time railing against regulation as he does supporting right to repair.
Right to repair is largely about protecting individual liberties and property rights.
What I'm saying is that by casting right-to-repair as leftist (or rightist) just muddies the waters of what leftism is without providing any guiding context about why people might be for or against the right to repair. In any case, there's very few parts of the governmental-regulation spectrum that are unambiguously left or right.
It's a bad legal concept, but it exists: The DMCA
Clearly, there is a legal concept of 'felony contempt of business model', as I did not coin that phrase myself.
People mentioned farmers in your sibling comments, are those consumers? I thought they are not.
Wanting more personal freedoms is generally considered a right-wing view. Creating a right to repair is about placing limits on corporations, not actual people. Try telling people that they can only use "original" parts in their guns and suddenly the entire NRA will be on the streets demanding a constitutional amendment in support of right-to-repair. This isn't a left-right political thing. It is a persons v. corporations issue, with government as the representative of the people.
The gun people in your example decided to use governmental regulation to protect their personal freedoms - which is definitely a leftist stance. Now they are on the right, but what you said moves them to the left.
The reason the gun people support the 4th amendment and still are on the right is because it's not a regulation that affects people, it limits the state.
Again, I'm not saying it's wrong to be a leftist. I support the right to repair too.
what does that say about the quality of what you have to say?
Usually their reason for that is to limit e-waste and unnecessary emissions. Thus I find it unlikely they wouldn't want this banned and fined.
