In the last 90 days they had 11 contributors that changed c,cpp, and c header files with at least 10 lines of code churn:

The user crsib appears to be the main contributor to audacity, so I would have to imagine others would have to pick up the slack for a fork to be viable.

cookiengineer also changed 71 files

https://public-001.gitsense.com/insights/github/repos?p=comm...

so he/she will have to constantly monitor these files moving forward, for the fork to be stable/similar to audacity/audacity, which I am not sure if he/she/others are interested in doing this for the long term, but I guess time will tell.

Full disclosure: I'm the creator of the tool that I linked to

Picking two applications with less global users than a small town or a large village doesn’t make a great point. They might as well have been abandoned - no relevant mass of people use them.

Ah, my bad. I'll stick to S&P Top 500 companies next time.

No, stick to forks that manage to reach a self-sustaining level above “one or two users cherry-picking from an upstream repo as a passion project”.

My point is that a fork can be abandoned by users even if the project is still active.

Your point is worth thinking about it, audacity needs a critical mass of users. But does it have enough original users to keep from being considered abandonded already?

Edit: to be clear, other software is often used instead of audacity. It isn't as well known as say photoshop, or maybe even inkscape.
