Yes, but only a small subset of OSS projects reach the tipping point of having a large enough developer community with people willing to taking care of it. They are the most popular ones, so we tend to hear their names, as opposed to the other majority of projects which have users, but no devs that could take the lead.

But of course, OSS ought to be, as I mentioned, a contribution to the greater good. If there are enough people interested in keeping something alive, they should be allowed to do so.

This is why pure communism is always a steaming pile as well. Who is going to fork it and feed and care for it? Sometimes projects succeed in the same way that road work eventually coalesces when a community needs a road, but many projects don't fit this mold and do much better with the drug dealer style of free for your first hit, then we charge you. Otherwise who is going to produce the stuff out of the wish to see a community do well without any benefit?
