That depends on the software and market, surely. If there's 5 open source alternatives, is it more important to get 6th for the minimal gain in freedom for the users, or is it more important to let the creator keep his freedom to share it under whichever licence he prefers?

What if there's 100 open source alternatives already?

An "alternative" is is not necessarily a factual alternative. I'd said if a solution has many users, the freedom of the users has priority.
