>If MuseScore was not acquired and continued down the current path, it would have been already shut down by now. This is what many people do not understand. MuseScore was going to be shut down if it was not acquired and a plan put in place with rights holders.
>Any site or system of distribution that includes copyrighted works and is done so under agreement with rights holders and according to their conditions will be shut down. This is simply reality.
The "excuse" for those behaviors is that they got to stay in business. I don't agree with all the actions of the rights holders but that's the way it is. If you feel it's better for there to be no Musescore at all, I would advise you to just not use the website. There's lots of other free sites that will host Creative Commons-licensed media. If you're looking for someone to negotiate hard against the rights holders, you would have better luck trying with a bigger company like Apple or Spotify.
