ECM was released at the same time as the Raven.
But I think you are correct about them delaying cause of MASC.
ECM was released as a module.. but ECM did absolutely nothing until ~2 months after the Raven was released... the same way that the Command cockpit in the Atlas DC is wasted tonnage since it does nothing right now. Always been there as a part of the mech but the benefits of it isn't in game yet.
