He and his wife are still the majority (perhaps only?) owners, so Linus is still in charge even if he is pretending to delegate some duties.
I think the fact he appeared in the latest video and was still so defensive is enough evidence to prove that point.
The whole reason "persecution" is the main talking point is exactly because there is no legitimate defense. There's not even an illegitimate defense that they can float to the base, so the only thing left is "witch hunt".
