Apple announced support for PCI in 1993 with their original PPC road map. The first gen of PPC Macs were Nubus for backwards compatibility but the second gen in 1995 were PCI. Apple allowed third party Mac clone makers to make hybrid Nubus/PPC Macs.

The first generation iPod was FireWire not USB and always had a proprietary file system for actually adding music and forced you to use either iTunes or MusicMatch (Windows) to add music.

Apple is no different than Googke or Microsoft. They use open source when it suits them but none of the major companies outsource their Crown Jewels.

But even if you go back to 1984, all of the other computer makers that made non generic clones are out of business except for Apple. So that's still 35+ years of Apple going thier own way.
