As in the title, do we really need a free tag? What is the utility thereof?
No, we don't need the free tag.
- In my opinion, this is a meta tag which does not inform at all about the topic of the question.
- You can't be an expert in free.
- The vast majority of the 24 questions with this tag are closed. This is associated to the fact that questions about 'free' stuff are most of the time off-topic/too broad for this site. (E.g. asking for free resources.)
I think we should remove it and add it to the blacklist.
