This is literally the storyline of the kids movie Robots where the bad guy (Greg Kinnear) makes it illegal to repair things, you can only buy new, and the robots who can’t afford new parts become outcasts but eventually there are too many of them and they rise up and with the help of the Ewan MacGregor and Robin Williams robots they overthrow the evil CEO robot, who it turns out, was really being controlled by his wicked mother (played by Jim broadbent)

(my kids have this dvd in the car so I basically have it memorized 🤣)
