Agreed on PNGs, but the original poster that the parent was replying to was even complaining about designers who give them HTML and CSS, because the HTML/CSS is auto-generated and isn't production-ready. They expected to hire a frontend developer who is also a good designer. The parent's point is that this is unreasonable: they're separate jobs and completely separate skillsets. (Not that such people don't exist, it's just not the norm.)
