This is precisely what is wrong with the Paywall -- people in the Uni don't know it is there.
Donald Knuth embarassed himself a few years ago when he told people that the library at the Uni was worthless because he can just sit as his computer and view all the literature for free.
Academics generally don't realize that the library at their Uni cuts a million dollar check to Elsevier every year, in addition to a number of other publishers. As a result, they don't see that there is any problem.
The other problem is that it cuts academics off from the rest of the world. Because paywalls effectively prevent non-academics from seeing what academics are doing, they end up being underappreciated, and their contributions end up being underutilized. And, since we might as well bring it back to money, I suspect it ultimately has a downward influence on the amount of money legislatures earmark for universities and research.
