That's no excuse, they can learn to use Gimp and FreeCAD instead of using Photoshop and AutoCAD. /s

I'm with you on this, but again, far fewer people even need things as heavy as Gimp/Photoshop with the web alternatives around. Stuff like Canva, even.

The accounting and finance departments of every business run on Excel. The Microsoft office suite is an absolute bare minimum requirement for people who work in those worlds, and it's the main reason Windows sticks around there.

(Office 365 may be changing that, though.)

In my experience, there's far less of this than one would think.

E.g. Yes, even my workplace requires crappy Outlook email, but the web is just as bad-slash-good.
