Challenging the logic of why it is or is not a good investment is healthy, screaming every nay sayer is a troll is a classic sign of cognitive bias, where you seek out only answers which re-enforce the view you want to be true.
This is true; however, the important factor has been known for a long time (that is, the specified cost of electricity and hosting). Regardless of the real or imagined motives involved in this cost, the number is still the same. Hypothesizing over whether CryptX makes profit from this figure does not affect anyone's calculations.
