And there are plenty of home routers out there at similar price points that are just as capable and just as simple. I had my Amplifi up and running in a couple of minutes and the only reason it took that long is I had to configure it for my Fixed IP.
There are plenty of good choices out there that are better than the Airports (I know, I switched from an Airport Extreme and two expresses to the Amplifi and solved all our weird WiFi issues) and the only way forward for Apple was either drop the product or spend engineering resources on a new mesh system. I am sure they looked ar Eero and Orby and Velop and Amplify and Google and all the others and decided there wasn’t any need for Apple to be in that space anymore because all of those products work and most of them are dead simple.
It’s as @MMTalker pointed out, Apple doesn’t make Laserwriters anymore, because that problem was solved.
