In all of the following I got a new thing looking for some new feature or because I could I guess, and had the older device outlasted the newer one: Bose headphones, any mobile phone really, Thinkpad laptops, Audi cars, Brother printers, any and all household appliances.
I really don't see the problem. Like you're saying people are buying new stuff because they want the new stuff, not because old is broken. There are tons of extremely cheap second hand things that could do the job and yet people keep buying new things.
How will this right to repair change anything? How much money was spent making it reality that could've been spent productively?
Note: whenever throwing those things out, save the knobs. They’re like $10+ each.
