Tech companies are laying off their ethics and safety teams.

Toward the end of 2022, engineers on Meta’s team combating misinformation were ready to debut a key fact-checking tool that had taken half a year to build. The company needed all the reputational help it could get after a string of crises had badly damaged the credibility of Facebook and Instagram and given regulators additional ammunition to bear down on the platforms.

The new product would let third-party fact-checkers like The Associated Press and Reuters, as well as credible experts, add comments at the top of questionable articles on Facebook as a way to verify their trustworthiness.

In their most recent earnings calls, tech executives highlighted their commitment to “do more with less,” boosting productivity with fewer resources. Meta, Alphabet, Amazon and Microsoft have all cut thousands of jobs after staffing up rapidly before and during the Covid pandemic. Microsoft CEO Satya Nadella recently said his company would suspend salary increases for full-time…
