Please don't apologise for poor treatment of customers on behalf of Apple. Remember the way they drove updates to iOS7, by essentially breaking all apps in the app store that weren't iOS7 friendly? Remember all the performance problems as otherwise perfectly serviceable older devices were updated to newer OSes they couldn't properly support? Remember how Apple provides no easy mechanism for downgrading again if an OS (or app) update does impair or outright break your device, nor any way to turn off the nags if it thinks you should upgrade even though all the reviews and real world anecdotes are saying the new version is a disaster?
Speaking of wives, mine has the same slowdowns as me. It happens on our iPads too. We like being on the same OS version so we have the same features and emojis and such. We have to let each other know when one of us gets tricked again into updating so the other can too. It’s a source of much frustration for us.
Whether it’s nefarious overtly planned obsolescence or just the “accidental” lazy kind where they put less effort into supporting older hardware, the effect is the same and it sucks.
I should get to choose to upgrade. Period.
Don't propagate the false "planned obsolescence" meme. It's tired and counter-productive, especially from a security standpoint.
