Microsoft's branding is mostly about time and should not be assumed to have any other significance. You might think you can guess what "Visual Direct COM" would be or "Active Windows.NET" but the words have no meaning beside "Currently this word is hot so my new product needs that word". A Copilot XBox Edge might be a video game console with AI but it equally might be a new version of Excel. There is no coherent rationale.
A company with an actual rationale names products PlayStation, PlayStation 2, PS3, PS4, PS5
Microsoft called their rival products XBox, XBox 360, XBox One, XBox Series
Asked to put six animals in order, some might figure Anteater, Bear, Elephant, Fox, Goose, Pigeon makes sense - alphabetical order, English names. Others might try to rank them by size, the Elephant is definitely bigger than a Bear, but is the Fox bigger than a Goose? Not sure. You might give them Latin names, there are several reasonable things you might do or at least attempt
But Microsoft are like that's easy: Elephant, Dog, Squirrel, Another Squirrel, Sparrow, Bear, Elephant. And like, that's not even six animals, and it's the wrong animals, and your order makes no sense, what is wrong with you?
How many times has Microsoft had some kind of product that isn't taking off how they wanted to, so they just rename it and give it a new coat of paint? Microsoft Office? I think you mean Office 365! What does that mean? Nothing, it's just Office but you don't get to decide when to update.
Anyway, now it's Office 365 Copilot! What does that mean? It means it's Office, but with an AI which you didn't ask for, which doesn't really do much for you practically, and also which costs 50% more, and you can only opt-out by trying to cancel your subscription entirely.
You can tell AI is a grift because it's all dark patterns and lies with these people.
Teams being rebadged Skype for Business being rebadged Lync is the biggest one.
To be fair to Microsoft, they do keep trying over and over again.
On my Android, it's called "M365 Copilot", which is even more wtf...
Just like most big corps, for a while they had a phase after Satya took over where it felt a new kind of Microsoft was coming, nowadays I would assert they are back to their former selves.
