Indeed, this is their only primary concern. They are a standard publicly-held corporation, after all. It is their legal obligation to focus their business in whatever way makes them, and their shareholders, the most profit. Were they a
B-corp, that might be different.
Eye health should be a much higher priority.
It is not a health issue, it is a preference issue. You are not being damaged by PWM. Inconvenienced, yes. Perhaps even severely so, and for that you have my sincere sympathies. However, until people who suffer from PWM achieve protected class status, there is no obligation for Apple or any other company to address your need. That is the unfortunate reality.
OLEDs are reaching critical mass in terms of marketing and manufacture. Soon, if not already, it will become significantly cheaper to source OLEDs at the scale Apple and other consumer product companies operate. Dismissing LCD displays, then, becomes a cost savings. How it gets spun as a marketing conceit is separate. Yes, there are specific advantages to OLED. No, those advantages don't necessarily matter to everyone, but marketing bullet points rarely matter to most people (quick: How many of Apple's top-line marketing B.S. "magical and amazing" talking points do all of you
actually use on a daily basis? I thought so. Same for me.) LCDs will disappear as OLEDs become cheaper and cheaper to manufacture due to scale. Demand follows scale in manufacturing.
And no, MicroLED will not be the savior anytime in the next decade. The technology is proving nearly impossible to scale beyond niche uses. A problem that will be solved eventually, like all engineering problems, but it will take far longer than some of the bloviated, inaccurate predictions paraded around in the amateur press.
