How Photoshop is used doesn't really matter - it's intended as a photo editing product. Adobe already has an illustration / vector product and there's a reason they're separate.
Which is why I never said it was that categorically so why the strawman?
But you know being a designer having worked with designers, having had a large design agency and done some work for Adobe I do consider myself fairly informed on the matter.
Whether you wanted to consider it a web IDE is besides the point. I remember the days when notepad was considered the gold standard.
If it helps you get the work done who care about what it was supposed to help them with.
I think you possibly have a limited perspective on what people are using photoshop, I'm pretty sure every professional photographer uses it in some way or another, for instance as are print designers.
