WannaCry for the Web
Malware, short for malicious software, refers to programs designed to act against the interests of the computer user. A recent (in)famous example is WannaCry, that abused computing resources to keep users from disposing of files present in their own computers as they see fit, so as to strongarm users into paying ransom for this ability. WannaCry relied on vulnerabilities in an outdated but widely-used proprietary operating system, but new vulnerabilities designed to let similar threats into your computer are about to be standardized into all web browsers! Don't you WannaCry for the Web, too?
Just two days before the Day against DRM, Tim Berners-Lee announced his decision to dismiss objections and approve Web DRM. EME, that per this decision will be in every standards-compliant browser, is not malware, it is rather the vulnerability that will allow malware to be automatically installed into users' computers.
This sort of malware, like WannaCry, is designed to act against the interests of the computer user, to abuse the users' computing resources to keep users from disposing of files present in their own computers as they see fit, so that the third parties who control the malware can strongarm users into paying ransom for the ability to dispose of the files, but not as the users see fit, rather as the third parties do!
So you see, EME is designed to open the door into users' computers for malware that's more restrictive on the user than WannaCry. EME might as well stand for Evil Malware Entrance.
