Well, no. In fact, for services which are purely free, complaining is really the only way to push for a change.
But it does mean that if you're complaining about something very far outside the core of the product, you're a lot less likely to be taken seriously by either the provider or bystanders, and rightfully so. And if it's a freemium service, you shouldn't be surprised that complaints from paying customers warrant more attention than free users.
