Measured consumer surplus from Facebook is quite high.

Judge as of 2019-07-18. True: published research measuring the consumer surplus from Facebook (for example willingness-to-accept or choice-experiment studies such as Brynjolfsson et al. or Corrigan et al.) finds large values (for example hundreds of dollars or more per user per year, or a large total relative to Facebook's revenue or to what users pay), and no comparably credible studies of that time find it low. Mostly true: most such studies find high values but estimates vary a lot or carry clear method caveats, so 'really quite high' slightly overstates it. Mixed: credible estimates differ widely, some high and some modest. Mostly false: the high figures exist but come only from narrow or outlier samples, and the main body of evidence shows modest surplus. False: the measurements available at the time show low or negligible consumer surplus.

   “For example, the median user needed a compensation of about $48 to forgo Facebook for 1 mo.”

   “we consistently find the average Facebook user would require more than $1000 to deactivate their account for one year.”

   “For instance, Facebook is worth about $40 to $50 per month for U.S. consumers, according to a series of surveys the researchers conducted.”

   “Regarding specific companies and products, the surveys found that consumers who use YouTube or Instagram place a lower value on Facebook.”

A peer-reviewed PNAS choice-experiment study published before the claim date found that the median user needed about $48 to give up Facebook for one month, roughly $576 a year (E1, E3). A separate study found that the average Facebook user would need more than $1000 to deactivate their account for a year (E2). Both figures reach the criteria's benchmark of hundreds of dollars or more per user per year. The only caveat in the evidence is that valuations vary between user groups (E4), and no study in the evidence finds the surplus to be low.
