In every protest, regardless of scale or cause, in gaming or otherwise, there are always people who'd go "shut up and take it, the best way to show your disagreement is through silence"... I don't get it.
I also don't see why protesting through user reviews is a bad thing. Whether it will get the developers/publishers to listen is one thing, but it will help keep any potential buyers aware of the latest situation. What if someone is tempted to buy GTAV because of all the mod gifs they have seen online? Not everyone is keeping themselves up-to-date, even as a gaffer, I can't say I know every latest development of games I play, or planned to buy.
Before you say "Everyone got the game anyway", I haven't, and I doubt I'm the only one.
I always check the user review section to see if the game is worth my money, there may be issues with the games, from missing features to poor performance. It beats going to Google and having to wade through hundreds of reviews that were done around the time the game came out, or asking here(or anywhere else) and then waiting for an answer. If a game recent reviews are all negative, I'd see what they say, then verify online.
Sure, Take-2 may choose to stay its course, but it doesn't hurt to try.
