It looks like you are looking at it from the political viewpoint instead of the practical one.
Google discovered that they already have plenty of white males working for them. They want more diversity and this course is their way to increase the pool of available talent.
Diversity (variety of backgrounds, experiences and viewpoints) is good for business. Google has many programs to solve different problems. This program is to resolve a problem of too homogeneous workforce. Don't read too much into it.
If I want a vegetable soup and I already have plenty of potatoes at home, I buy what I am lacking. Will you criticize me for discrimination against potatoes? I posit that all the indignation about this particular program omitting white males is as silly as criticizing me for omitting potatoes from my shopping list.
I also agree with other posters that attacking and denigrating any group will drive some of its members away, even if they are otherwise interested, talented, and competent.
