But if public opinion is mobilized as a weapon through very selective presentation of the issues in ads, in a disproportionate way that leaves the public with a skewed picture of the pros and cons, it has the same indirect effect of pressuring the politicians to act in the company's interests. The public can't react in their own interests if they don't have the right facts, so then polls will legitimately show what the company wants, by and large.
Roughly the same problem arises if they fund a heavy "lobby your elected officials" campaign, targeted only at their supporters, with no equivalent resources mobilizing those who disagree - and indeed they did this.
