For me, the really objectionable part isn't the "thievery", it's the sloppiness of it.
Anyone with half a clue knows that if you're copying HTML:(a) you'd better redact any references to the original source, (b) you ought to change the class names, and (c) you sure as shit better not link to resources on the owner's servers. After all, most HTML/CSS is borderline protectable under copyright in the first place.
P.S. If you're copy/pasting HTML/CSS, you're pretty terrible at web design. Anyone with even the slightest facility in web design could whip up a clone of the 37Signals landing page in an evening without doing more than sneaking a peek at the source.
