It would be ironic if the (presumably) most highly paid male within Microsoft increases his salary by paying women more in raises then men, just because they are women. The overall effect will be an increasing disparity between the most lowly and highly paid employees (contrary to his supposedly Marxist background).
He's certain to succeed and get his bonus by simply instructing his minions to hire and promote more women. But hiring / promoting more women is simple, the hard problem is addressing the gender disparity of available skilled employees, and students interested in pursing a career in the IT profession (assuming this is a problem that really needs solving).
Nadella also wants Microsoft's hiring practice to represent the global population (which is code for more ethnic minorities). This is fair enough given, Microsoft is a global company, but this is a justification for creating more jobs and finding more customers across the world. It's not a justification for bringing the rest of the world into the west to undercut or replace the existing workforce. Doing so brings global companies into a conflict of interest with western workers. Western governments represent their voters not lobbyists of global companies. So they should recognise this conflict of interest and support their voters interests first.
There is clearly a political agenda motivating this (top-down rather than bottom-up / grassroots). Their agenda is presented as moral but is not the truth. Frequent news headlines suggest the IT industry is inherently sexist and discriminatory. Future generations will read those headlines and believe it to be the truth. IMO this is a serious misrepresentation of the industry, but if CEOs are willing to accept this, then they must also accept responsibility for the apparent historic discrimination that has taken place within their organisations.
