If you read all the war asset descriptions, everyone DID upgrade their ships with Thanix guns. Salarians, Geth, Quarians, Alliance, Turians. Most likely they just didn't have enough on-hand industry to get every ship a thanix gun or refit the dreadnaught's 1 km cannons for them in time for the battle for Earth. And who's to say the Reapers don't have a defense against their own weaponry? Thanix guns just leveled the playing field a little. Reapers are still damn tough.
