I think this is the right answer. I am frustrated by Copilot and by many aspects of AI, but to me it seems like straightforward branding: you use a Microsoft product, you want to use AI in it, you look for Copilot (name and/or icon).
To me, the issue isn't that they've named so many things 'Copilot' but rather that Copilot is in every goddamn product.
You are the second person that implies that "Copilot" is just a complement that identifies part of some software...
Microsoft has been replacing most of their brands by Copilot. There's no searching for it in a product, the product is named "Copilot".
