Why put links to "paid for" papers

Once again, a press release has a link to a paper that you have to pay to read. No less than $30!

For a US Government lab, this is pretty rich.

It really doesn't make sense to put out this sort of thing.

Maybe there will be an accessible copy over on the password protected area of EurekAlert! But I am not holding my breath.
