Consider the danger he will be in just prior to release. Perhaps Lin's tweets are meant to keep POTUS safe by basically informing the Deep State that he (Lin) has everything Trump has, and if anything happens, multiple other people are primed for release.
This warning is not just a warning from Lin but also a warning that people other than POTUS know EVERYTHING.
Bringing any very famous Deep State character such as GWB on stage in front of a million people and live on T.V speaking and providing evidence of it's own evilness and of other famous DS characters would work just fine to convince a much larger number of people than only playing videos that would obviously get flagged as deep fake.
