Your description of what these companies do is distorted. They are not actively developing technologies with the purposes that you described or even as any such consequential purpose.
Posting a Google search doesn't offer any convincing argument to support your supposition about the intentions and/or results of these corporations. I do understand what you're trying to say about these corporations, but the way you represented it is misleading at a minimum.
