I read Crystal Beasley's post, and the comments, and she's absolutely not snide at all. Everything she's saying is not only true and respectful, it's not even controversial. In general, coders don't know what to expect from user experience designers: yes. Developers don't have good judgment procedures to know whether proposed designs are correct: yep. And so on for all of her points.
If you think there's an additional point to add regarding high-handed designers who don't listen or collaborate effectively, you haven't actually read the post, in which she says: "The solutions to all these problems lie in communication and building a trusted relationship. It’s a higher barrier for designers that takes time to overcome. I've found all of my team to be receptive when I've taken the time to explain the principles that guide my decisions." How in the world is that snide, or trivializing the problem?
