Earlier quoted context omitted.
They don't own the no-CD crack. So technically, they are selling software they pirated.
They are also (arguably) selling software written/designed/intended for the express purpose of bypassing copyright protections, which as I understand is in and of itself a no-no under the DMCA regardless of underlying ownership. I ANAL of course. edit: per the sibling comment the crack might not be included, so this might not apply.
The "regardless" part is wrong. It is permissible for the owner of the software to include software for the express purpose of bypassing the protections they themselves placed on their software. Why would you think that the software owner isn't allowed to do that?
