I get what’s the author is trying to say, but, as a maintainer of a small, free, open source project [1], I’m really happy to get more users:
- having more users helps to keep motivation
- it helps also with the credibility: we work in a large telco, and popularity can justify us working on it on our work hours
- we get more feedbacks, more bug reports and so we improve our tools. As we use it intensively, it’s benefit for us
When your project reach a certain level of popularity, maybe you don’t « need users » any more but I think the majority of GitHub projets are small, relatively obscure, and can benefit from feedbacks, usage etc…
