Hey Krita is a great case to make but I would characterize it as the "exception to the rule" not the rule of open source software.

Photoshop is a bit of a leviathan and it's odd how no one has ever really competed with it strongly and the software has certainly suffered from its lack of real competition.

There's also the reality that its primary users -- designers, photographers, digital artists and the likes, aren't usually programmers or techie people who use a large variety of complicated software, and so for its primary users, they know Photoshop like they know their Canon, they know the details of the brand and setup and change is hard for them as well.

EDIT: To corroborate this last paragraph with an anecdote, I asked a digital artist friend of mine if she'd used Krita, and her reply was: "I'm leery of open source though. like great for devianart and stuff but often find saving problems, glitches etc", so that helps demonstrate how ingrained artists can be to their tools.

Krita seems great -- but that doesn't make Ubuntu better than W10 or OSX, and it doesn't mean that LibreOffice is in the same decade as Word and/or 360 or Google Docs, etc etc.
