It would be nice not to waste our votes!
Let's all sign the same petition on Change.org (or sign them all).

In addition to the petition reported by Nick Norton in this post (https://makemusic.zendesk.com/hc/en-us/community/posts/25930028335383-Open-Source-Finale), "Release Finale Music Notation Software to the Open-Source Community" @ https://chng.it/Jbn7rhgvNb , I also found another one.

Please, also check out "Urge MakeMusic to Continue Developing Finale Notation Software or Open-Source" @ https://chng.it/9KmbhdhyGS

Let's make our voices heard against the sunset of Finale!
