If this was as obvious and well-known as you make it seem it boggles the mind how a primarily hardware company like Apple missed this. I suspect hindsight is 20/20 here. I also have two Nvidia Apple Intel Macbooks (one of which lives in my trunk) that weren't bit by this. Anecdotes, you know.

I'm sitting next to my 2013 Mac Book that I still use daily for occasional testing. The thing just won't die or give me any issues. Anecdotes.

They at least have the Apple Store available (show me another consumer hardware manufacturer that has anything similar), and needless to say your experiences (again) don't match mine. I've been to multiple Apple Stores in multiple states time and time again and never experienced this. The last time I was at their EXTREMELY busy store on Michigan Ave in Chicago I was in and out inside of 15 minutes. They just handed me a brand new Apple Watch (no AppleCare even) and offered to set it up for me (declined).
I'm not sure what's going on in your world but my social circle is almost exclusively iMessage-blue and I've never heard anything like this. Quite the contrary, actually, and reflective of their overall great reputation for customer service and support.
