The Ops has a point I believe. While the side switchers, for the most part, do not abuse the TG control, there will always be at least that "one" individual that will take advantage of it. Prohibit their ability to take command of the TG solves that problem.
Just last week player X took command of Rook TG, then got side switched with him still in command. Now that he was switched sides, he can not access the TG to release command. Chan. 200 was full of demands he release command but he couldn't.
