No health experts will be guided by these new guidelines.  

Everyone with a functioning brain knows more testing leads to reduced virus spread and less testing leads to more virus spread.

CDC guidance matters. Hospitals, schools, workplaces will be using these guidelines.

Well then, prepare for a mass explosion of virus spread in a few weeks.

OF, why do you believe that? IF all close contacts are in quarantine anyway, it will have minimal effect at most. If OTOH the close contact has chosen to disregard the necessity to quarantine, why do you believe a positive test (although he feels fine) will change his behavior? Couple that with the fact the contact may not yet test positive because the incubation period is not yet up and you probably don't have a "mass" anything. In fact, a negative test may cause somebody who actually was quarantining to decide "Screw it, I tested negative, I feel fine, I am going to work", even though two days later they are still asymptomatic but shedding virus like mad.

I have no idea why the CDC changed their recommendations. Obviously, some believe it is political influence. That is what makes Trump's behavior so reprehensible. If the CDC is doing it for political reasons, that is bad, and if people believe it is being done for political reasons, even though it is not. that is also bad. Unfortunately, because of Trump, we don't know.
