IDK but Mossad is quite possibly the world's most effective spy agency and SV software corporations rarely have effective safeguards to protect against rogue employees so we must conclude that there are many sleeper agents planted throughout major corporations on behalf of just about every intelligence agency in the world including but not limited to mossad.

I have not seen any hard evidence of this nor have i ever suspected a fellow employee at any of my employers of being a double-agent loyal to a state intelligence agency but it's easy enough to do that there must be hundreds, maybe even thousands of sleeper agents all over santa clara and redmond.
