Many years ago, Adobe claimed that Apps would be equal

of course they have different tools.  they're different apps that perform differnt functions.  you would hardly expect and text editor to be part of a sound editor.

it's the organization of meus, the use of panels and the ability to import a file created from one app into (some) other apps that creates the adobe ecosystem.

When Adobe was buying out other companies, they said "all applications will be interchangable".  

...any stockholder should claim fowl (sic) and Corporate mgt.

I've been using Adobe applications for 35 years and don't recall ever hearing "all applications will be interchangeable". I don't even see how that could happen! Each app is unique and serves a specific purpose. When Creative Suite started shipping, some things were changed for consistency, such as shortcuts and the location of the zero point. I don't see anything foul here.
