That's neither anti-White nor misandry; its not saying there is a problem with either whites or men, but that there is a problem if your careers page and/or exec team bio seem to indicate both that its all white men and also there is no signal of recognition that diversity matter.

Note that the end of the paragraph containing those two sentences is this: When you’re a small team and those are the cards you’re dealt, it’s harder to get around that. But you can always put a statement on this page explaining the fact you want to diversify your team and why. Another trick I’ve seen is having a clearly female silhouette saying “This could be you!”.

i.e., if you want to attract people that aren't white men, you need to show that you want to attract people that aren't white men, rather than showing signals that you are a bunch of white men looking for more white men.
