- slowing down customer-purchased devices before pushing new devices to the market. Not every Apple user wants, needs or can afford new phone every year or two
- forcing users into SaaS model via secretive security updates. One can't have secure device (well, secured up-to-date, not saying that fully updated iPhone is secure) without Apple gutting existing software, changing UI/UX and doing whatever they please on the device customer has paid for, against the customer
- blocking the possibility to upgrade the OS to previous version. IMO many versions of macOS and iOS were downgrades in comparison to previous ones. We couldn't rollback iPhones and now we can't even install macOS that came with the computer. Just the newest one (at least that's my experience: every installer but the newest one crashes at the very end)
- pushing their agendas by forcing EVERY Apple device to download a shitty U2 album because Tim Cook says so. That's what I will remember Tim Cook for the most.
Jobs was not ideal but he had drive and imagination. The company he largely participated in building was something different than your usual corporation. Cook is just an unimaginative pencil pusher.
