The ACM is probably never again going to publish a paper as influential as Liskov's paper I mentioned above, or Knuth's "Structured Programming With go to Statements", or "Go To Statement Considered Harmful" https://dl.acm.org/doi/pdf/10.1145/362929.362947, or Schorre's "META-II: A Syntax-Oriented Compiler Writing Language" https://dl.acm.org/doi/pdf/10.1145/800257.808896, or Ken Thompson's "Regular Expression Search Algorithm" https://dl.acm.org/doi/pdf/10.1145/363347.363387, or Dan Ingalls on "The Smalltalk-76 programming system design and implementation" https://dl.acm.org/doi/10.1145/512760.512762.
Papers like those are the ones that we need to protect our ability to archive and distribute. Not David Geerts's "The Transformative Power of Inspiration" from the current issue of CACM https://cacm.acm.org/careers/the-transformative-power-of-ins.... (I am not making this up.) Thompson was competing with, let's say, Mooers and Schorre; Geerts has decided instead to compete with Jesus, the Buddha, and Norman Vincent Peale, and my brief reading of the article does not offer much hope for his prospects.
It seems safe to say that in 30 or 100 years' time nobody will cite Geerts's article as a turning point in the human understanding of inspiration, so if it's lost due to copyright restrictions, it probably won't matter that much.
At the other extreme, scholars seeking to understand the historical origins of object-orientation or personal computers would be crippled without access to material like Ingalls's paper. I'm not speculating—I'm speaking from experience, because lacking that access, I grew up thinking C++ was object-oriented!
But what do we see on the current version of the Ingalls paper that the ACM's web server just gave me? A note added in 02002 prohibiting public archival and redistribution:
> Permission to make digital or hard copies of part or all of this work or personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.
