"Torrenting from a corporate laptop doesn’t feel right," Nikolay Bashlykov, a Meta research engineer, wrote in an April 2023 message, adding a smiley emoji. In the same message, he expressed "concern about using Meta IP addresses 'to load through torrents pirate content.'"
By September 2023, Bashlykov had seemingly dropped the emojis, consulting the legal team directly and emphasizing in an email that "using torrents would entail ‘seeding’ the files—i.e., sharing the content outside, this could be legally not OK."
Emails discussing torrenting prove that Meta knew it was "illegal," authors alleged. And Bashlykov's warnings seemingly landed on deaf ears, with authors alleging that evidence showed Meta chose to instead hide its torrenting as best it could while downloading and seeding terabytes of data from multiple shadow libraries as recently as April 2024.
