Yes I know that concave bars were a limitation, obviously if I was sarting a new SA GB today I would use the new molds. It's completely different to make kitting changes before or AFTER the GB. You're giving people something different than what they bought.
I did the poll for everyone that I could, which is geekhack and my discord. You're right that it would be ideal to poll every single customer but I can't do that, especially since I had limited time to gather customer feedback and make a decision or it would start hurting production times.
I can't read people minds, I'm not gonna assume what everyone wants, I'm gonna use the data that I could gather to make a decision and I'm going to prioritize not making kitting changes after GB unless a significant percentage wants it. If someone bough the set it means they are okay with concave bars or they don't even know the difference, so it's not that terrible to just give them the product they were gonna get from the start. There's several previous SA sets like this, it's fine.
In any case I don't know why you're so worked up, I'm not ignoring anyone, I'm not acting like I'm doing anything noble. Relax.
Unbiased and hopefully helpful input on the disconnect to at least fill in some of the blanks.
I think maybe what is frustrating some folks is that, post-SA Mizu (I know it was marketed for SA Dualshot as well), the option for convex spacebars has been known - so there was a missed opportunity out front (some may have even assumed the bars would be convex based on this). Additionally, without stating what "significant" means in terms of a number of buyers voting for a certain option, it's really hard to understand why a healthy majority would not result in a modification being made, especially if you as a designer have polled for input and did not want to be making a decision unilaterally...
I understand the reluctance to make changes after money has been taken and the GB period is over but, to be frank, I don't think you should have polled for this option at all if you did not take additional steps to maximize the number of buyers participating, make a decision based explicitly on the results alone, or use designer discretion if you truly believe convex bars to be a better choice. In my experience, if you request feedback and make a decision that is counter to the feedback received, people are going to lose trust. This is a fair response in my opinion and, while nothing can be done now, maybe this perspective can help clear up the level of frustration in this thread.
