Interesting discussion of how the program was developed.

Musescore is quickly becoming more and more important in today's engraving environment.
Before it was only because it was free, now it is also able to create decent output.
What worries me is that its staying free is fuelled by the MuseScore subscription, which gives people access to hundreds of thousands of scores in PDF, XML, Musescore format. Without too much effort, one can easily find copyrighted music that just should not be there. Complaining about it doesn't bring too much, sadly.

It has always to stay free because the license doesn’t allow otherwise. The subscription instead fuels the professional development leading to the massive engraving improvements and better usability. However, that doesn’t invalidate your point about copyrighted music.
