If you’re an Apple VP right now, your concerns are about branching into new industries like driverless cars or heads-up displays. A graphical bug on one OS isn’t going to perturb you.
A lot of the flack going Apple’s way should be directed at the lack of innovation in the rest of the industry. If Apple felt their smartphone dominance was actually threatened, you can be sure the focus would be put there.
This is the price of the success Apple fans like myself were hoping for through the OS X era.
