“Be like Feynman” is great advice for 0.01% of the population, and horrible for 99% (and irrelevant to the remainder). In order to be valued for bluntness, one must be correct insanely often. Otherwise, you have to share evidence rather than conclusions, and couching it in more pleasant terms makes it much more tolerable (again, for most but not all).
Bluntness has nothing whatever to do with not sharing evidence, so this seems like a total red herring to me.
