Okay, so ... community. A company can listen to it and act on that. Works great if small, and basically every user is speaking up.
At some point though, communities grow, become more diverse. At that point, either the company is going to get called out for catering too much to the specific group that's consistently speaking up, the people that are speaking up can get dismissed as a loud minority, and an assumption of a 'silent majority without complaints' sneaks in.
Soooo... not all decisions are always going to be made by communities or the outspoken parts of those...
