OH: Facebook knew for years ad reach estimates were based on ‘wrong data’ but blocked fixes over revenue impact, per court filing.
Some more internal emails Facebook really doesn’t want you to see: Turns out in 2017 COO Sheryl Sandberg had already known for years there were problems with a free ad planning tool the company offers to marketeers to display estimates of how many people campaigns running on its platform may reach, per newly unsealed court documents.
The filing also reveals that a Facebook product manager for the “potential reach” tool warned the company was making revenue it “should never have” off of “wrong data”.
The unsealed documents pertain to a U.S. class action lawsuit, filed in 2018, which alleges that Facebook deceived advertisers by knowingly including fake and duplicate accounts in a “potential reach” metric.
Facebook denies the claim but has acknowledged accuracy issues with the “potential reach” metric as far back as 2016 — and also changed how it worked in 2019.
Read the whole, ugly thing.
