Ayelet Gordon-Tapiero & Yotam Kaplan*
ABSTRACT
Social media platforms have become enormously powerful, accumulating
wealth at an alarming rate and influencing public opinion with unprecedented
efficiency. Platforms use algorithms that promote discriminatory, divisive,
extreme, and false content. In recent years, content promoted by social media
platforms fueled a series of calamities: the spread of disinformation during the
COVID-19 pandemic, the January 6th insurrection, and the establishment of
dangerous trends among adolescents and children. The platform crisis is here
and is showing no signs of abating.
Platform algorithms recommend divisive, hateful, and inflammatory
content because such content encourages users to spend more time on the
platform, allows platforms to collect more user data, and presents users with
more advertisements, generating more revenue. Thus, the most socially harmful
algorithms are the most profitable for platforms. This profitability is fueling the
current crisis: as long as harmful algorithms remain the most profitable, new
catastrophes are sure to come.
This Article argues that any effective legal response to the platform crisis
must address the immense profitability of harmful algorithms. These Authors
further suggest that this type of legal response is possible through the doctrine of
unjust enrichment. This proposal explains the conditions under which platform
profits should be considered unjust, and how the doctrine of unjust enrichment
allows courts to strip platforms of such ill-gotten gains. This Article breaks new
ground in being the first to study the doctrine of unjust enrichment as a remedy
to the platform crisis. Rather than prohibit a particular type of content or a spe-
cific optimization metric, this proposal targets platforms' financial incentives,
forcing them to consider the broad societal impact of their choices. This is a
promising legal venue, offering tools that are unavailable through other frame-
works. This Article further details the advantages of this proposal, explains its
origins in existing doctrine of the law of unjust enrichment, and provides a rich
account of its implementation in practice.
