Apple is just bitter that they didn't notice this trend, whereas Google executed beautifully on it. Chromebooks have come a long way and these days can do 95% percent of what users need. A bought a Pixelbook, when they first came out, and haven't had to touch any other computer. A lot of things are on the web these days, and everyday it's more. Most companies are moving all their workflows to the web.
But Chromebooks aren't limited to that. They also run Android and Linux apps. In fact, my Pixelbook is the nicest Linux laptop I have ever owned. Everything just works out of the box. No more tweaking drivers all the time.
And that's really the big news. All other computers, Mac included, require constant maintenance and you always have to be worried about malware. ChromeOS nicely eliminates all this hassle. Things just work!
I recently bought another i7 Pixelbook off of EBay. At less than $400, it is hard to pass up on. Took me five minutes to be up an running, and another 15min to copy my Linux environment from my old computer. That's so much better than anything Apple can claim to do. They'll never have me buy another one of their products. Also, they keep adding gimmicks like a touchbar for function keys, but then they miss out on useful features such as being able to convert my laptop to a tent or tablet configuration when I want to share a presentation with others.
My Pixelbook is not only cheaper by a factor of almost 15, it's simply a better more useful device for most people. The only exception is things like heavy video editing. But that's a niche market. If you need it, then of course, get a powerful expensive machine. Most of us don't need it though.
