I have raged at Sibelius numerous times when I was told "It's the best music notation software out there." Finale, the other big corporate music notation software, touting itself as more user friendly, has a garbage UI. It's because of this YouTuber that I found out about MuseScore (for which he's worked on the UI), and I was psyched to see he's part of Audacity as well. I'm fully switched over to MuseScore now, and I'm staying there. Plus it's FOSS!

As someone who is in software development world, I can say not everything is to be blamed on developers.

Managers often only look at graphs and ignore the users. User's don't matter, their money does.

Now am not defending this company, but still...
