No, it hasn't stopped. There are two key factors which determined the lack of need for newspapers in this year's Tour.
Firstly, there were no cool days during the race, even in the mountains. Secondly, the highest altitude they had to descend from was about 2,100m.
If they'd had to descend from higher cols like the Galibier, Iseran, Bonette or Agnel (i.e. in the 2,600m to 2,800m altitude range), or even the Izoard, and if the valley temperatures had been 20C instead of 25-35C, they would have been grabbing newspapers as before.
