The -sa clause is only relevant for derivative works, not for simple
reuse. However, the legal code of both cc-by and cc-by-sa requires
that "You may Distribute or Publicly Perform the Work only under the
terms of this License. You must include a copy of, or the Uniform
Resource Identifier (URI) for, this License with every copy of the
Work You Distribute or Publicly Perform." (section 4a,

IANAL, however, so I'm not sure that this is the relevant part to
apply and, in any case, it's up to the author to defend his/her
copyright.
True, they ought to link to the license. I think we have to be happy
with what we can get, though! As long as they attribute it, they
aren't doing too badly. Once we've got people used to writing "Source:
Wikipedia" we can start on getting them to do everything by the book.
