What W3C is doing is correct. It is republishing our copy of the RSS specification under the terms of the Creative Commons Attribution/Share Alike license and using our preferred authorship credit: RSS Advisory Board with a link to https://www.rssboard.org/.
The RSS Advisory Board has published the RSS 2.0 specification for 20 years. Over that time we have revised it 10 times, mostly in minor ways such as to fix a broken link.
The board began publishing the spec under a Creative Commons Attribution/Share Alike license when Dave Winer was still a member. It is redistributable under the terms of that license forever.
Winer wrote this on his blog in 2003:
"On July 15, UserLand Software transferred ownership of its RSS 2.0 specification to the Berkman Center for Internet & Society at Harvard Law School.
"Berkman then placed a Creative Commons license on the spec, allowing it to be customized, excerpted and republished. ...
"The spec can circulate freely thanks to the Creative Commons."
