You did good by publishing this. I've seen that you're updating your blog post based on what people are saying here, you don't have to do that, you don't have to answer to people attacking you on a forum.
What you have exposed has the potential to affect a large number of Google users and unfortunately the community has chosen to attack you over attacking Google.
Which could say a lot about the state of the community. So thanks again for bringing this vulnerability to our attention.

Maybe you don't feel like you have to, but I can tell you from experience, that when an entire community of your peers piles on to you, there is a significant emotional response that you're being rejected. That's just my personal experience, but it seems pretty common to want to respond when those you respect and work with (or might work with) respond negatively to your work.
