The so called 'rampant' covid misinformation has nothing to do with Facebook's design as the authors claim. People have been spouting BS on various internet forums/platforms since - forever. The article takes a very real problem (employee accessing users' private data) that actually is a design flaw, and then overreaches by dumping a whole bunch of claims and leaving the reader to connect the dots.
It makes a lot of unsettling assumptions that we the users want zuck and co. to essentially bless facebook posts with truthness scores and prevent people from being wrong on the internet. Sorry, I don't want them to determine the truth of anything anyone says. Facebook is not a nanny!
Aside, is this website actually associated with MIT?
