I've seen this question covering why we don't need to add an explicit VtC option to covering licensing questions.
However, it would seem to make sense that, if we're going to close questions about licensing as off-topic, it might be worth including that fact on the What topics can I ask about? page in the help center (as a topic you cannot ask about, of course).
The contents of that page do seem to be specific to DBA.SE - including a line that says something like:
- Licensing - Questions on licensing should be referred to the vendor, and an answer obtained in writing from them.
wouldn't seem to make that page too unwieldy, and avoids the need to link to a meta-discussion as to why it's off-topic.
I can see that some things might change with time (whether MS Access or BI is on topic, over the course of years, could change (BI would probably be off-topic if a Business Intelligence Stack Exchange site were created, for example)), but since the licensing issue is a legal one, I don't see this as something that's likely to change over time.
And, the closing of licensing questions seems to be a matter of tribal knowledge - I don't see anything about it in the
faq questions, the help page, the tour.... I only know about from seeing such questions get closed. Which leads me to believe that we need to manually comment on every one, so the asker knows why it was closed.
We tell people not to ask for career advice there - why not licensing, too?
