As someone looking in that hasn't voted one way or the other on this thread, I would say it's because there's been no substantiation of the claims being made, even after it was specifically asked for.
HN does not look kindly on people that make definitive claims without evidence, and especially not on those that refuse to provide evidence when then requested. There are less inflammatory ways to make the statements presented here, and ways to do it with evidence. That wasn't done.
I have seen the "breaking changes" aspect discussed multiple times in the past, and Steve has even addresses it in a prior discussion (linked to by him from this discussion)[1] and this thread itself farther up[2]. If you respond to him there with any questions, I'm sure he would be happy to answer or point you to relevant discussions.
