In fact, even the people who made the game (did the actual work, not managers, advertisers, etc.) don't get to decide.

Correct me if I am wrong but the programmers, designers, artists have already been paid and any money from sales goes to the company and its execs/shareholders.

(And yes, employees can also be shareholders but they almost always own such a tiny share it does not really matter. In a just world, ownership would be distributed automatically according to time_worked * skill_level.)

EDIT: I might have overstated by saying it doesn't work but it definitely doesn't have the same level of effect as people collectively saying "this behavior is wrong and you will be punished for it, regardless if I buy the product" (for example by editing laws). It also doesn't allow any control over how the money is distributed among those who worked on it (compared to for example adding a law that limits absolute/relative spending on marketing - whether you think it's a good idea or not).
