Red Flags everywhere
If you believe the strategy laid out in the parent comment to yours, then it isn't a red flag at all. For the last 10 years, the number 1 thing that contributed to Apple's growth was the iPhone. They don't believe that will be the case for the next 10 years.
I think they should release those numbers for investor clarity, but I don't think it's a red flag.
I realize iPhone is an amazing amount of their revenue, but they are transitioning to a services and accessory business built around iPhone. It’s less important exactly what model iPhone you have, in my opinion.
Reducing investor visibility into a publicly traded company when numbers start turning negative is a huge flaming red flag.
Well, I think the console makers do.
