If you wish for only positive feedback, you are in the wrong line of work.
It's not about comments being positive or negative, it's about how those comments are made. You can critique a game without being a complete asshole about it. Like, say something like "Not a fan of Lucky Chloe. Have seen too many idol characters lately" instead of going all Comic Book Guy on some dev.
I understand that having a bunch of little shits criticize your game or movie based on merits like "shit looks so lame" is infuriating, but be real. 9 times out of 10, no news is good news. Tekken has a dedicated fanbase, myself included, and Harada is gonna make bank regardless of what neogaf or redshit has to say about it. Same as Michael Bay's ninja turtles, Ben Affleck's Batman portrayal, and so on. Replying to the snot nosed 13 year olds with this kind of "feigned rage" is childish. You've still got hundres of thousands of fans who will love the game and the character, so why go to the trouble of baiting fanboys and nerdy fucks alike? Seems unnecessary.
I agree, but I can think of two reasons to do so:
1. Marketing. News like this goes beyond the usual fanbase. It's good to have a loyal group of players, but most franchises can't survive of that alone. You need to draw in new people.
2. This was the last drop and he wanted to say something for his own sanity. Fans on the internet are great as shitting on everything that doesn't meet their every demand and once you become aware of that, you have to be really thick skinned to be able to ignore it. (I think that as long as devs have a decent sense of humour about it, they deserve a free punch once in a while.)
