As a counterpoint, comapre that with eg. reaction to QuickJS, when it was announced. People did not know who's to be credited for most of the work (only that two people claim copyright in the code), but if you look at the comments, it's all praise for the better known name, Fabrice Bellard, and almost no mention of the other person.
People will praise who they want to, and will bother to verify, only if it disagrees with their prejudices in the first place.
There's also a difference if those prejudices are based on something like past achievements of the praised person, or on something unrelated, like being a woman.
