For individuals and groups, yes, yes we should... but for mega corps whose customers are from every background, its safer to be neutral... You don't step on any toes when you're not taking any sides...
Not taking a side is tantamount to condoning injustice.
Like google gives a fukk about some fringe white supremacist group boycotting them....the world can't NOT use google at this point, same with facebook....these companies have literally nothing to lose by being benevolent and supporting an oppressed people.
My girl has a small YouTube following and they sent out an email to people with more than like 5k subscribers saying basically "the black community needs your voice and help...don't be a dikk and promote hate."
