I think it's largely because of the title, which suggests that this (and JS + HTML canvas) is technically innovative in a way that it isn't. As long as they're informed criticisms and not too aggressive, that's a good thing.

Plus you (and others reading) might learn something. Better than having a sycophantic echo chamber.
