I suppose that makes sense, but literally everything a camera sensor (+ image processing chain) does affects the final output in some way or another. The CFA, the demosaicing algorithm affects color, the optical low-pass filter that's designed to remove aliasing from high-frequency artifacts ends up reducing sharpness in some situations, things like dark-current suppression affect the image, etc, etc, etc. Every camera brand bakes in tons of processing. But those features are designed to be beneficial in most cases, and this article is about the edge cases where some faint stars, in some photographs might look a little different if you examine the image at 1:1. Its an interesting article from a technical standpoint, but I'd say the feature does more good than harm in the vast vast majority of situations. Also, most dedicated astro folks, especially the ones doing deep space imaging (i.e. beyond just capturing the mikly way) are probably using dedicated astro cameras.
