Well, imagining it from the buyer's perspective, if I bought Audacity then now I can make changes to it and while there may be other forks, these changes will be likely be recognized as "the" Audacity.

So if for example I wanted to cross-promote my other products or add a "pro" paid version of some sort, I could do that, and those would end up in the main version most people are downloading.
