Last I heard a Mac is a PC. Hey even phones are PCs. They're all personal computers. In fact I would say mac's are more often PC then windows machines. Windows machines are often not personal and are used my many people in big orgs in a shared corporate fashion.
Lol. I haven't heard someone define mac's and PCs as different like that in a long time.
Apple did an amazing job to market it as such and create an us and them division. Imagine Tesla started marketing themselves as 'we're not a car, were a Tesla'
Doesn't mean they should never be put right either. Just because something has been called something that it should always be called that. That's seems to be big thing in western society at the moment.
I disagree. Pedantry adds no value, and moralizing semantics seems silly at best. What counts is that people understand clearly, and in this case everyone did.
