1 - if people don’t want reactions based on the title, they shouldn’t make clickbait titles.
Not my title, it is the video creators and i suck at writing short descriptive titles

I'm not a programmer as I'm not interested in programming and end users are not likely to be programmers either, what the video points out is that open source projects can benefit from having non programmers on the team like designers and program testers as well a keeping the end user in mind for program usability
Just watch the whole video, it explains way better than my comments can
Krita is more suited to digital art as someone who is using it to learn art
