Let’s try to understand your logic here.
Logic #1:
Let’s say Mozilla decides to drop Firefox and leave it up to the open source community to maintain the web engine, add new features, etc., where will the money for development come from? You know, seeing as the money donated to Mozilla doesn’t support the development of Firefox.
Logic #2:
Or are you just using the wording to say something like, “It’s not exactly accurate to say donating to Mozilla funds Firefox development. It funds other things related to the open source internet, rather than only Firefox. So, again, it’s not an accurate statement to say that people should donate to Mozilla to fund Firefox.”?
Logic #3:
Explain if you want.
