Sounds to me like Apple is worried that they're losing the photography war, that Google is doing a better job of giving people the photos they want.
Personally, I really like the fact that my Pixel gives me a group photo with everyone's eyes open, even if there was no single millisecond in which no one was blinking[*], just for one example. My family with iPhones all take several shots of each group photo in attempt to increase the odds that one of them is good. I get one shot and know it will be good -- and that's what I want from a phone camera.
This is a really interesting debate to me because I'm a photographer. Not a pro, but a moderately-serious amateur, good enough that I semi-regularly do portrait work, weddings, etc., (though what I really enjoy is wildlife and landscape photography), and people are very happy with the results. And photographers never talk about "taking" photos, but about "creating" photos. Angle, composition, lighting, exposure, depth of field... there's a lot that goes into creating the image that you want even if without any post-processing. After the shoot comes the editing, and every photo is edited, even if the editing is nothing more than tweaking the color balance and cropping. Usually it's quite a bit more than that, sometimes even full-on "photoshopping". Even journalistic photography includes a lot of editing (though it shouldn't include photoshopping).
What Google is doing is automating much of this, so that non-photographers can create nice-looking photographs without the effort. Of course, sometimes the automation will get it wrong... but my experience is that my Pixel phones are incredibly good at giving me good results. They don't have the versatility of my DSLRs, thousands of dollars of lenses, filters, lights, and significant time in post-processing, but for creating memories of family events, vacations, etc., Google's phones do a great job, and I often don't bother with the DSLR any more.
[*] The way this works is that the phone actually grabs a few dozen images, before and after the shutter button is pressed, then the software picks the best one and swaps faces in from others as needed.
