Apple has always been focused on usability and simplicity at the expense of power. Remember the one button mouse or first desktop without any external media options?

But also, do you really think causal users care about Thunderbolt 3.1? Or previously, Firewire 800? And want a $3000 laptop that can drive two 5K screens?

I realise you talked about the OS, but it's the same deal. Apple OS'es were always dumbed-down compared to Windows - just compare the control panels and application "installation" features. Have you seen Group Policies?
