Most things related to fittings are not discovered by one person alone, discovery takes place across the universe, nothing in EVE stays secret for long.
The cloak+MWD trick is old, very old, and it's really never been much about that as most players assumed this to be working as intended since small and agile cloaking ships should have a reasonable chance to run a gate camp. For larger ships the cloak+MWD doesn't matter as they don't get far and can easily be decloaked. In addition, very few players actually fit a cloak on a battlecruiser or battleship hull.
The problem is with the game mechanic as such. Cloaking previously didn't cancel modules that work based on a cycle duration (such as MWD, rep, and ECM). What folks were doing is using a Falcon (or other ECM ship) to target a ship, enable the jammer, and cloak right away.
This allowed the skilled ECM pilot to reliably jam half a dozen or more targets (round robin) without any risk at all. Clearly that was not intended.
It took CCP a good three and a half years to fix it, but now they did. It's done, no whining will change it back, moving on.
