You don't do this out of the goodness of your heart to inform other people how bad the company is, you do this purely to maximize the probability of receiving any sort of compensation from the company. Most people (?) would only consider this route if they genuinely feel that the company has egregiously wronged them, because it's a big, low-probability-of-success pain, and airing dirty laundry is easier and often more cathartic.
If you have already decided that informing other people is more important to you than a settlement (or have concluded that the effort is not worth your while), then fine, you've made a different decision, and perhaps the commons are better as a result. But if you decide to air the dirty laundry, you'll usually lose the ability to change your mind later.
