Some Facebook employees are reportedly angry at company leakers for compromising the tech giant’s culture and have pushed for them to be punished, according to internal Facebook documents exposed by whistleblower Frances Haugen.

Facebook is now getting more secretive by recently rolling out a new “Integrity Umbrella” system, The Verge reported. The Umbrella keeps a list of workers on its Integrity team, which focuses on making the platform safer for users, and only grants the 6,000 employees on that team access to certain sensitive internal documents and tools.
