By far the most common certain demographic response seems to have been to claim that it’s fine that literally none of Overwatch’s 25 playable characters is a black woman because line up includes robots, an ape and a hamster… so naturally is the most diverse range possible.
That of course, is not even vaguely what “diversity” is about and even Blizzard executives Chris Metzen (now retired) and Jeff Kaplan (definitely not retired) understand that:
The problem is: Overwatch got prematurely rubber stamped for “good diversity” primarily for having higher than the (abysmal) industry standard for female, brown and old lady characters. (ie, some characters exist).
Now they’ve got that kudos, they’re not interested in actually delivering on promises or even maintaining the baseline.
Well it’s either that, or they decided that a key demographic who needs over representation is conventionally sexually attractive white women. Specifically ones who are almost identical to Widowmaker. [link]
Blizzard already has a bad track record for disregarding concepts of characters of color in favor of making them white and blonde (specifically Mercy and Junkrat) and otherwise ignored concepts for characters of color that they’ve showcased for PR but apparently will never develop
There is seriously no way that anyone can believe that Blizzard, as a company, have any interest in good representation and making everyone feel welcome beyond sound bytes and quick stunts they can do to seek publicity boosts.
