No it's not, it's disappointment, and if there's one word that can sum up what has happened to BD and this game, I cant think of any better.
Disappointment is not a base emotion. Disappointment is made up of surprise and either anger, disgust or sadness. Since you're complaining about someone, it's anger or disgust.
If you can sum up the entire development process of WVM with "disappointment", then you clearly haven't been correctly adjusting your expectations. Otherwise there would be no surprise, and thus no disappointment.
And as I've alluded to in other conversations, it's unhealthy (and unproductive) to waste your anger or disgust on trivial things. It doesn't make your life better, in fact, focusing on negative things in your life that you have the power to cut yourself free from makes your life worse. And by default, anyone here who is angry about WVM's development has the power to cut it out of their lives and seek out new things that do make them happy.
I once bought pre-order No Man's Sky. When the game came out, it didn't have a lot of things it promised. But rather than get angry, I decided that game was not worth the money I spent on it or me getting pissed off. Instead, I uninstalled the game. Never played it again, even when there was some PR thing about how they fixed it years later. I learned not to pre-order video games unless I had confidence in the dev. I view Patreon in the same way. I don't pay for WVM. Never have. But I do keep an eye on new releases. Because it's a good game even if the dev's professionalism is lacking.
To me, that's the healthy way to look at it. And again, anyone is free to disagree. I've always said that it's subjective, I just shared my (rather easy-going) view on the situation to help other people see that it's all about how they choose to look at it.
