I haven't heard anything about the ATE blue dye causing issues . . . ATE is actually the same company as Continental-Teves which is one of the biggest ABS module manufacturers in the world. I'd be very surprised if they didn't do full testing of their own fluid on their own parts.
But, to be honest Ford HD fluid is more than enough for anyone here. It has excellent fluid boil properties and is dirt cheap from the Ford dealer.
