It still blows my mind that people claim this is true. Almost all CS papers are on the author's website, eprint, arxiv, etc. Google scholar even links to them.
Don't get be wrong, closed publications are a travesty. But they are a travesty because institutions pay out of government grant money (indirectly via overhead) to pay for subscriptions and because it's government funded research. They are not, at least in anything approaching the average case, a travesty because researchers cannot access results.
The primary link is almost always to the canonical version which is usually the pay walled one(even if it's not the most in depth version the author wrote). Did you check for the links on the right hand side? Those are the pdf's that google found. Of a pseudo random set I clicked on, all had links.
If you search little bit more, you would be be able to find that work somewhere else for free download. Some application paper published by Springer etc are difficult to get.
