Friends, at a time when science is under attack and people are economically hurting, the scientific community should work to make access easier not harder. @ACM, Association for Computing Machinery, is doing the complete opposite by introducing paywalls that didn't exist.
Features that were previously free and open to the public are now "Premium
Access" features.
If you are opposed to this measure, join me in signing this petition asking the ACM to stop.
