OP's have brought up several good points. Here are a couple more thoughts. Lin has mentioned several times (and has posted the picture) that he met with Trump in the Oval Office on March 11, 2020. He has specifically named that date more than once. He has shared few details from that meeting other than that he told Trump that he firmly believed God had given him this task at this time and in this place. However,

Drop 4 refers to military "intellingence" and state secrets. (And we know misspellings matter.)

Drop 60 says "You can count the people who have the full picture on two hands. Of those (less than 10 people) only three are non-military. Why is this relevant? Game theory. Outside of a potential operator who has been dialed-in w/ orders (specific to his/her mission) nobody else has this information. Operators never divulge. Alice & Wonderland."

My theory/guess (with minimal sauce!) is that Lin is definitely not one of the 10, but I believe he is an operator who was dialed in with orders specific to his mission in regards to certain "intellingence" at that meeting (and possibly other meetings/contacts). It is also of interest to note that just 2 days later, Trump declared a national state of emergency in regard to Covid. How (or whether) the two events are related in any way, I have no idea, but it's an interesting correlation.

Obviously, none of us have any idea what Lin knows or what his assigned role is exactly, but I think it's a very safe assumption that he knows significantly more than we do and has a very important assignment to carry out.
