I too find their naming conventions confusing. Apple TV is another example. It could refer to 3 different things depending on how it’s used. I have an Apple TV and an Apple TV subscription but I have no idea which is technically called what.
I also disagree with their casual use of the term “Pro” too. But at least that isn’t an Apple specific problem but rather endemic across the entire tech landscape.
The Microsoft example given by the GP isn’t great though. Microsoft are, in my personal opinion, even worse at naming things than Apple. But as someone who’s released a fair amount of open source, I do acknowledge that naming things is hard.
