links for tabs?

I'm writing in regard to a question I have about the How to Meet WCAG 2.0
QuickRef <https://www.w3.org/WAI/WCAG20/quickref/>.

I notice the developer has chosen not to use the ARIA Tabbed Interface
pattern <https://www.w3.org/TR/wai-aria-practices-1.1/#tabpanel> specified
in the ARIA Authoring Practices
<https://www.w3.org/TR/wai-aria-practices-1.1>.  I understand the arguments
for why one might choose not to go this route, but wouldn't it be more
semantically correct to make the tabs buttons at least, on the general
principle that "buttons do things" (in this case trigger a disclosure),
while "links go places"?  Is there a reason for using anchor tags here,
instead?

Best,
Rob
