I honestly think the person that is to blame here is you. Yes, there might be some weird decisions here, but if you get so mad about those minor changes, you should make at least some research before updating.
Updating is not a choice. The most you can hold off is 1 year. If your phone is eligible for the next iOS, you don’t get security updates. Many apps I use already require 17.0 as of today.
Meh — I see where you’re coming from, but this post is about Apple violating design principles, not a pity post about this particular person. We’re all to blame for everything in our lives on some very basic level, but it’s no excuse for the negligence of others.
