Why is dumb don feigning compliance with Science since he is the greatest disrespecter of science the world has ever known? WHY PRETEND?

After many decades of contempt and disdain for SCIENCE he is now rolling over for it complying with it lying down for it? This is very weak of him. He usually stands his ground and doubles down. Why is he BACKING DOWN? Whassup with the dude? What's his game this time?
