From the Washington Post:
On
Facebook, you decide whom to befriend, which pages to follow, which
groups to join. But once you’ve done that, it’s Facebook that decides
which of their posts you see each time you open your feed — and which
you don’t.
The
software that makes those decisions for each user, based on a secret
ranking formula devised by Facebook that includes more than 10,000
factors, is commonly referred to as “the news feed algorithm,” or
sometimes just “the algorithm.” ...
Amid a broader backlash against Big Tech, Haugen’s testimony and
disclosures have brought fresh urgency to debates over how to rein in
social media and Facebook in particular. And as lawmakers and advocates
cast about for solutions, there’s growing interest in an approach that’s
relatively new on the policy scene: regulating algorithms themselves,
or at least making companies more responsible for their effects. The big
question is whether that can be accomplished without ruining what
people still like about social media — or running afoul of the First
Amendment. ...
One way to regulate algorithms without directly regulating online speech
would be to amend Section 230 of the Communications Decency Act, which
shields websites and apps from being sued for hosting or moderating
content posted by users. Several bills propose removing that protection
for certain categories of harmful content that platforms promote via
their algorithms, while keeping it in place for content they merely host
without amplifying.
