Totally junk or skewed to ignore sugar as a contributor? Again I have to immediately doubt your dire accusations because they diverge from what is said in your link as well as what my physician says about cholesterol.

And it's not like the 90s pyramid had sugar at the base.

Yes, largely junk. As I mentioned the literature is full of studies that are nothing but some regressions on top of self reported dietary data. It’s almost all very low quality[1].
