I've dealt with Japanese people for a long time, and what I'm seeing here is people trying to avoid a person who is being disruptive and rude. And I'd be miffed too, because your writing style comes off as arrogant and entitled.
I don't mean to imply that this is how you are in person, and I'm sorry that this will come off as an attack, but business communication is something that you'll really need to work on if you want to successfully contribute to larger projects (this is nothing to be ashamed of; Linus Torvalds had to take lessons, too). I'd also remove that blog post if I were you.
