Twitter laid off about 40 data scientists and engineers working on advertising late Wednesday night in what amounted to at least the third round of cuts since mid-December, according to a person with direct knowledge of the layoffs.
The layoffs targeted areas that Twitter’s leadership considers to be failing, such as the ads product, and unimportant, such as data science, the person said. Twitter’s ad revenue has reportedly plunged in recent months, as advertisers respond to Elon Musk’s loosening of rules around content moderation and the general chaos as Musk shakes up the company.
