My initial instinct is to agree. But then, your second statement is overly broad when you say "on the network" (even assuming you are referring to the Stack Exchange network). The Software Recommendations site is, of course, explicitly set up for that purpose.
But to your point, it's hard to find another SE site where these questions would be accepted, and to which we could redirect them. Neither Cross Validated nor Data Science (the latter of which is in beta) seem to accept this type of question, and they would be the obvious alternatives.
But consider the relevance. This movement/community (dang it we have to find a term which covers software - OSS, FLOSS, Free - and everything else created in a "here's the source" manner) is not new - I was using GnuPlot back in the early 90's - but it has reached critical mass. It is beginning to accrue a body of case law; it is impacting the revenues and business practices of companies around the world; it is enormously influencing the lives (whether they know it or not) of hundreds of millions of 'ordinary' people through the products they use every day.
If research doesn't exist, then it darn well should. It's time someone started to quantify and examine the importance of our contributions.
Perhaps allowing these questions will prompt some research. Certainly, via google, it may direct researchers and journalists to this site. And if this site is to be something more than a reference on which license to use, then the questions offer one more way to expand its scope and make it relevant to the entire community of creators and users.
I would also point out that two of those questions have attracted quite a few votes (at least for this stage in the site's life). That implies that this community is interested in the answers
It looks like the Open Data site will accept some types of "where can I find data about ..." questions. So part of my original answer is now slightly less persuasive to me. However, the second part (on relevance) still seems worth considering.
