Ripped off open source without attribution

On the one hand, it’s nice to see an easily accessible hex editor in the Mac Store.
On the other hand, all this app has done is take the BSD open source code for Hex Fiend, compiled it, *removed the attribution and copyright and any acknowledgement of the author*, and posted it here. But pointing to their own web site.
They even directly copied the marketing points verbatim from the open source project.
Please don’t reward this type of behavior.
