I’m bring this up because I saw some people proclaiming we can use Creative Common licensed items within SL and with the Linden Lab Terms of Service (LL TOS). This is an area where people have to sort out intention, time, and who/when complexities to make decisions.
To actually know what one can do in this regard you must consult a licensed intellectual properties attorney and even then you will only get an opinion. Until a judge rules on a matter it is all opinion.
Going back a bit in time, many think the legal panel discussions (UCCSL) in SL revealed we do not grant SL ownership. Their idea is the TOS only APPEARS to do that but not really. Also, that it was never the INTENTION of LL to take ownership.
You can hear the panel discussion (3 hours) from links in my article: Second Life TOS Update 2013-42.
