Whilst I see your point, the problem here is not "people want Science to be a source of truth" but rather "people want Science (and other journals) to strive for the truth", which is subtly different. A part of striving for truth is being interested in cases where you were wrong as well as right. Science has given the impression here that they don't care if astonishing claims turn out to be false. This is the sort of behaviour associated with tabloids. Is Science an entertainment magazine or is it striving for truth? The standards of behaviour expected are different.
