I'm as white as they come, but I personally don't get upset about this. Racism is discrimination, discrimination implies a power imbalance. Do people of all races have equal power nowadays? Can't answer that one. I couldn't even tell you what race is, since it's an inaccurate categorisation humans came up with that doesn't really exist in nature (as opposed to, say, species).
Maybe a good term for this could be "colour washing". The opposite, "white washing" that defies what we know about history, is (or was) definitely a thing. I find it both weird and entertaining to be on the other side of this for a change.
Google has more power than these users, that is enough power to discriminate and thus be racist.
> it doesn't seem that important
You might not think this is important, but it is still textbook definition of racism. Racism doesn't have to be important, so it is fine thinking it is not important even though it is racism.
Which direction were they going, actively ignoring a specific minority group?
