A shill is someone who promotes a particular opinions not because s/he honestly holds it but because s/he is paid to.

Please show us your evidence that Neil deGrasse Tyson says what he does about NASA not because it's what he thinks but because he's paid to do so. You do have that evidence, right? Because you say repeatedly that he's a shill. Apparently you even know how much he's paid to do it ("He's a cheap shill"). So, evidence please.
