Sure it's misinformation, but it fits the politically correct narrative.
Let me translate. First, he acknowledges that Cosmos has been legitimately criticized for itsinaccurate portrayal of the history of science. But he wants to defend Cosmos, playing the "devil's advocate." Why? Because the "naïve view scientists advance" -- that science is always good, and religion is always getting in the way -- might be more "useful" when talking to the public, even if it isn't "right." But what does he mean by "useful"? And is he really suggesting it might be OK to lie in the service of defending the prestige of science? Yes he is, and that becomes clear in his next comment:
There has been a lot of this "selling out the principles of scholarship for political reasons" thing going on recently.
