From Buzzfeed:

Alzabarah and Ahmad Abouammo, a colleague on Twitter’s global media team, regularly accessed and delivered information that could’ve led Saudi intelligence to identify anonymous dissidents. While news of the allegations against them has been public since November 2019, the extent of their roles and abilities inside the company have never previously been reported. Alzabarah, Abouammo, and al-Asaker did not respond to requests for comment.
