Patching....
There's three ways to do patching
Control just the software and spend years refining the patching process with vast amounts of in house testing to ensure 90% compatibility and then if anything breaks you did your best
Abdicate responsibility for the delivery of patches to 3rd parties who are only interested in selling new stuff and customize your OS so everything will break, then its their fault when stuff does break or their customers get hacked.
Control Hardware and software so patching is simple and pushed to every device (except where they pass control of patching to third parties for some hardware who ......)
Two of them work, one doesn't, take you pick
Class action anyone?
