Apple's built their entire company on dropping backwards compatibility. It's how they've maintained their agility for so long, despite being one of the largest companies on the planet.
Especially nowadays it seems their biggest asset became that they produce good PC-hardware on such a high economics of scale that they're almost unreachable in build-quality...
I’m not so sure. We love to complain about Apple, but I don’t see many old timer Mac users now extolling the virtues of Windows. It’s dangerous extrapolating one’s own observations to the world at large, so maybe I’m wrong?
This might be true, but macOS in general is not what made Apple one of the largest companies on the planet.
That's not about complaining, it's about correlation and causation. It's like saying Apple's Wi-Fi routers must be the best because Apple became one of the largest companies on the planet.
I'd say without the iOS ecosystem they would be a well-respected company in the premium tier of their industry, like Dyson or B&O.
I switched to mac circa 2003 and reliably connecting to wifi was simple, clean, and intuitive. This was the height of the shitshow that was wireless networking on windows, where half the time windows would fight with the vendor software, etc.
I was even more shocked when I hit the "advanced" button and there was full and working advanced BSD networking settings cleanly laid out, from overriding IP/netmask/router, 802.1X, etc. Windows made it difficult and frustrating to apply these kinds of settings, because they wanted to hide it from the user.
Mac and macOS are afterthoughts at this point.
At some point you need to move on. Can’t support ancient platforms forever.
