And in any case Thrawn is still only talking about the specific fleet at Endor. Hence why he starts out by saying "Yes, Captain, you were there,"
"Not at all, Master C'baoth," Thrawn told him, his voice perfectly calm again. "My analogy with combat borg implants was a carefully considered one. The Emperor's fatal error was in seeking to control the entire Imperial Fleet personally, as completely and constantly as possible. That, over the long run, is what did the damage. My wish is merely to have you enhance the coordination between ships and task forces - and then only at critical times and in carefully selected combat situations."
Sounds like it refers to more than the Battle of Endor, yeah.
Thrawn says he only wants C'Baoth to do it in combat situations, and not constantly like Sidious did it.
And the "you were there" refers to the fact that he was there in the moment (or the fight) as the fighting spirit of the Empire died.
