I agree, I think Harry missed the golden opportunity to change the critics' (or even cynics') view of Meghan and himself, where they are pushing equality when it suits their agenda. Had Harry at least engaged or even acknowledge that white working class boys are one of the lowest admission to university and underperformance in school, he could have turn things around of being balance and not bias of just pushing one particular side of argument/agenda. On the other hand, I could understand that he is uncomfortable with class, given that he is from a very financially privilege and well socially connected background. And he probably does not want to be perceived as a champaign socialist like some celebrities and politicians.
This is what I felt as well, Harry seems to be speaking Meghan's opinions that does not necessary applied to British society. His speech appeared to be "imported" from America. Again, Meghan probably does not understand that class (or SES) is the one of the biggest division of UK society, not just race. She either does not know or deliberately ignore (as it not suit her agenda) ongoing issues within white working class. Cynics and critics would certainly believe it's the latter, given that at one point Meghan was pushing the decolonisation of university curriculum and tackle the dominance of "male, pale and stale academics", or even "white privilege" and "male "privilege".

Again, I agree with you that Harry's speech appeared to be lecturing and preaching ideas primarily from Meghan. The term "unconscious bias" has been very controversial in UK politics. Apparently up to 40 Conservative MPs refuses to take the Unconscious Bias Training, which is voluntary. Some of their responses were very strong to say the least. I assumed some Conservative Party members would feel the same.
