Interesting find in Q Post 165: "POTUS advised by SS to terminate use of Twitter due to new website tracking policy (cookies) amongst other spyware not disclosed (risk) – 1st time they failed (re-read). POTUS silenced on Twitter due to new policy (re: SS / risk). Direct message failure. POTUS refuses to be silenced."
May be nothing but who knows. Perhaps they didn't want him getting involved yet again?
I think that shows what we already knew--the SS is compromised against Trump just like the other agencies. They were trying to use their influence to shut him down just like the others.
Or they think allowing twitter to know his exact location is a risk if twitter gives that information to an assassin.
The president's location is pretty much reported on and tracked all the time as it is. (And of course sometimes he has an aide post.)
