I'm not a fan of the style, but I don't see how its defining visual characteristics are significantly more geared toward the political correctness safe route that you seem to be portraying it as. At least not when compared with illustration styles that employ a similar degree of abstraction.
In the the 8 years that Adobe employed a similar style, starting in the mid 90s, it clearly managed to do so without even an inkling of diversity: http://splashscreens.sourceforge.net/acrobat.php
Depending on the year you look at, the 90s version is less abstract than the current examples we're discussing here, but some years are actually more abstract. The lack of diversity is fairly clear to me regardless of that variation.
Of course, whenever we analyze abstract visuals, biases come into play. So maybe this read above is rooted in my own bias (either in favor of being able to make a point here, or in regards to how I believe a 90s corporation would portray "the business user"), but I think that's a stretch in most of these examples.
