I still truly don't get the connection between "the EGS exclusivity and refund/Steam key thing sucks" and "Yu Suzuki/YsNet is personally responsible and sold out the fans"
Did YsNet/Yu accept a deal with Deep Silver? Yes, to bolster the funds to make a better game for the fans. Everything Deep Silver did from there they did with almost certainly little-to-no input from YsNet, who have been sleeping in their offices (at least Yu had) to work more on the game.
Basically, it was option 1 or 2:
1. Kickstarter funds only - a smaller game, less refined (can't afford to delay game and stretch money for that extra time), without any stretch goals that weren't reached during the original campaign. Game gets released on Steam and PS4 at launch
2. Deal with the "devil" - DeepSilver and Epic get involved - additional stretch goals are reached, bigger (and presumably better) game as a result. Marketing goes from non-existent to decent, more people are aware of the game. Epic dollars, based on prior estimates, help to make it a much bigger chance that fans will get Shenmue IV (and no, they will not be going back to Kickstarter, I'm sure of that). Game gets released on EGS at launch, PS4 backers are not affected and get a better game.
As a fan, I'm glad that those of you that wanted a refund are getting one, I really am, but to act like YsNet and Yu are doing this solely out of greed and to attack them personally is utterly ridiculous.
