> It's virtually impossible to live in modern society
If you truly consider those "multinational companies" to be so unethical and dastardly, then don't. Live outside of modern society. Many people do. You do not.
> how is this different from a simple proposal that dissenters simply leave society ?
It isn't. If enough people leave, the old society disappears and a new one forms. If not enough people leave, then the people who left were morons and suffer for it. As simple as that.
The funny part is, everybody knows the above. It's a part of human nature. It's how new societies form and old ones disappear.

Your hypocrisy is telling.
