PNG isn't being subverted. The lossage happens before PNG is applied.
What you are getting is a lossless copy of an image that has been cleverly preprocessed to be easier for the PNG algorithm to compress while not losing noticeable visual quality. The result is good compression and transparency support (which JPEG doesn't have).
