Thing is, to some people, it feels like there is an agenda to reduce, wipe off the map straight, white males. So naturally some people see this and they think 'here we go, sjw's have won'. The western world is slowly becoming more diverse, great!! but, at the same time, it should reflect society naturally and organically. The western world is still a predominantly white race, just as asia has their ethnic groups and majority and alike, so naturally, more white charaters will dominate. No one is calling for bollywood to be diverse where equal casting takes place as an example... so it's problematic, for no reason - just represent, simple. Hollywood should reflect society, but it has to be honest about how it goes about it.
I have said all along, what needs to happen is they need to keep Bond as he was created, old school money, posh, blah blah, bit of a dick around girls, everything that people don't like right now, it seems... just because, that's who he is. Make the supporting cast around him diverse, like it is in the real world. When people go to watch the movie, if they like bond, good... if they don't, tough.... but at least on screen everyone gets to see an aspect of themselves.
Further more, the oo7 code can be anyone's.... and this is why a proper origin story for a rebooted bond can show him gaining the title, perhaps after the retirement (hopefully not forcefully) of an agent.
