If you don't say anything people will just walk all over you, or be oblivious to certain things.
Vocal communities like this are good, if the reviews have to get hammered then so be it. It's about sending a message.
Vocal communities opened Bandai Namco's and Sega's eyes to the market available on the PC, they expressed their disapproval for paid mods which caused them to get pulled. (Which may have recently made a return).
There are many other things vocal communities have done which have lead to positive things.
What became of some of them? Sega brought more games to PC, Dark Souls and it's sequels came to PC, many publishers have since acknowledged that there is a huge market for their games on PCs, and that's because the community was vocal about it.
EDIT: I would like to mention that I am for the concept of compensating mod creators, how a lot of people handled the paid mods thing was wrong, including attacking mod creators for getting involved and advocating for it's removal entirely. This was actually a bad thing overall, as adjustments weren't made to the system and people had conflicting interests. Perhaps this is a showcase of a bad outcome from the vocal community?
My issue with it was that I thought the cut of mod creators was a bit low. Mods have helped sell copies of games, an example would be a mod such as DayZ for Arma 2.
Fortunately it appears to have returned in a more polished state, with Bethesda's Creators Club, I'd like to see what becomes of it.
