All this proves is that people are unwilling to make a value judgement. To most consumers, having the "highest tech choice" is more important than having a repairable device. To really put one's money where their mouth is with repairability, one would have to show that they value repairability even if it comes at the expense of other things they value.
It proves that corporations can create small monopolies (over repair of their products, etc.), and use their economic advantage for more economic advantage, leading to true monopolies.
I literally cannot vote with my wallet when there is a monopoly. That is the problem here. This legislation is about preventing a company from claiming a monopoly over repair of the products they sell.
