No. By this logic, giving any organization power is giving power to the people, because all organizations are "essentially groups of people". But that's clearly fallacious -- in all but the most bizarre cases, the local warlord's crime organization isn't nearly as representative of the will of the people as a democratically elected local government.

Companies are not democracies. Especially multi-national corporations and the lobbying arms of entire industries are in no sense representative of the will of the general public -- or even of their own employees (see unions)! This is significant because it is categorically not possible to actually choose not to interact with a particular corporation. In fact, the historical truth of that observation is the root cause of environmental, health, and many other regulations.

A defining characteristic of democracy is one person, one vote, and it is that characteristic that safeguards the will of the people. There is no corporate structure (other than unrepresentative radical experimental structures) that even conceits to affording one vote to each person. In fact, there's no provision of the TPP that requires the suing company to be publicly traded, so in some cases it may not even be possible to buy votes.
