Illustrator, in my opinion, handles this properly. It greys they menu item out. It's frustrating to accidently click 'Open in Bridge', which then automatically opens up CC and installs the app.
The menu item should just be named "Open Bridge"... As it does not actually automatically "browse" to a previously saved, open/active document (which the script above does do).
I agree that having all the CC apps treat the function the same would be nice, but it's now a yeaer later and Adobe hasn't adopted this idea. OTOH, it isn't at all difficult to edit the PS menus to hide "Browse in Bridge" and edit the keyboard shortcuts to disable its shortcut. It's a one-time operation, and I just did it this morning after my Abyssinian cat walked on my keyboard and installed Bridge for me.
