Are you both forgetting that uncloaking and instantly opening fire with or without RP is against the rules? Not looking what you are typing is no excuse.
Restoring the ability to talk while cloaked (which makes about zero sense) would enable those people to circumvent the rule.
(And some people are already uncloaking, /l1-ing and shooting in the timespan of 1 second while hoping no one is taking screens like mad)
