First, the question you should be asking is "Is there a consensus among the community", not moderators, as it is the community here who runs this site. Diamond moderators are here to handle exceptional circumstances. The 5 users who voted to close your post are all users of Project Management Stack Exchange who have contributed enough to gain the close/reopen privilege. Closing and reopening questions is part of the regular workflow for all users with at least 500 reputation, in order to help ensure we get the best content possible. This helps attract great project managers to our site and makes the Internet a better place.
Is the question a good fit for Stack Exchange?
Stack Exchange, all Stack Exchange sites, are Questions and Answers sites, meaning that questions are expected to be written in a way to where there is a finite answer or at least a handful of answers without there being infinite possibilities. The first part of your question is as follows:
Looking for ideas on as many licensing models as possible...
This is what Stack Exchange refers to as a polling question, and over the years we've learned these questions don't fit well with our Q&A model. First, it's difficult to evaluate which answers are more "correct", since every answer can be correct, and second, it creates a lot of noise making it harder for future visitors with a similar problem to quickly determine if the question or answers will help them. For idea generation, a traditional forum may be better than a Stack Exchange site.
Is product management on topic on Project Management Stack Exchange
The meta question you referenced was asked on day 2 of this site's private beta. We hadn't even gone public yet. A Stack Exchange beta site goes through a pain period where the community tries to figure out what the site is about, and in the early days, we weren't sure.
I thought there was a question brought up more recently about product management on this site, but I can't seem to locate it. However, it was discussed in-depth on Area 51, but the proposal for Product Management has since been deleted since the product management community has been unable to get enough committed users to launch a site. Thus, I am unable to reference any of the discussions.
I do recall that the product management community wasn't interested in merging with Project Management SE. The folks who posted insisted that project management and product management were completely separate domains.
We've not made it official, but it seems to me that product management would be off topic. If anyone from the community would like to weigh in, please do. Furthermore, those who think the two product management questions should be closed can use their close votes to put those posts on hold to help eliminate any future confusion about our site's scope. Hope this helps!
