Without having to read the 100 page license agreement i am not sure as to if i can use those 2 plugins (as the agreement is universal). From the linked thread you mentioned it seems like i can use any asset i want (free) as long as its removed before submission (if i can't re-distribute it). What that means to me is that i can make a game and use a first person controller from unity then remove it at submission and have a non functioning camera basically ruining my game. The whats the point of adding it in the first place if you are to only remove it later.
