I worked at an electronics place a while back and I remember there were issues in an old chip in some older products. Not talking anything major here but a few known bugs that could have been fixed. But usually nobody had the time allowed to go fix up the old firmware on old products because there were always other things to deal with that were deemed to be a higher business priority. Unfortunately there's often more money to be made by the manufacturer by making the costs of these bugs externalities on the entire market than there is to be made by fixing them. Even when vendors have large budgets to work on security work done on end of life products ends up being typically abandoned because there's just more money to be made elsewhere at the moment. Open source chips could help deal with this end of life issue.
