ACM members can offer their papers open-access legally and for free, helped by the ACM.

ACM has an authorizer service that allows you as an author, to publish special links on your personal website, that will offer all visitors of your personal web-site free downloads of your papers.

Those who are interested in your paper don't need an account, they just need to click on the special links published on your website and the paper will be free to download in PDF.

A lot of the relevant authors are already dead, and many more of them will be in the next ten years, so this is not good enough. It may reduce ACM's conflict with authors but it doesn't particularly help a researcher who's trying to track down a result someone published in CACM 40 years ago.
