I kind of feel OP didn't need to add his opinion in this case, just brought the article to attention. That said, I favor very much that original posters should have an opinion, not just ask what others think, as frequently happens (it is sort of like playing a boss here which naturally irritates).
Froome's bike is top of the line and that probably makes it into a more sensitive machine than more tried and true tech on production bikes for the rest of us. But if those disk brakes are what anybody can buy, then what he says should be of concern, mainly that about pistons rubbing. What is more damming is that his bike is serviced by pros. That should give a pause to the rest of us.
