According to ancient Apple ads, a "Mac" is not a "PC".

Macs fundamentally can't be personal computers since they're entirely controlled by apple. Any computer running nonfree software can't be a personal one

lol so the IBM PC isn't a PC?

There are free BIOSes.

IBM didn't ship any on their PC

So? You can replace the ROM chip (or flash it, if it's an EEPROM). The whole point of free software is that you don't have to limit yourself to what the manufacturer says you can do.

Now that I understand it, this is an excellent point.
