There are certain people that have taste receptors that taste broccoli as very bitter.
They won’t like it no matter what.
This says they will, when eating it enough times.
It seems bizarre.
I love BROCCOLI RABE ... the Italian version which is described as bitter.
I go to lengths to find it in specialty stores,,,and it costs about twice as much. but, along with a good Italian Sausage, [and lots of garlic], it makes a great pasta sauce!
