What does Hotz's work have to do with piracy? Is that it's sole purpose? Can it be used for other legitimate things? Are you seriously going to compare videogames to porn? Porn is an industry where people don't want anyone to see them buying it because of cultural stigma, games are not anywhere near that level. Sony did not have anywhere near the level of cracking going on until they removed Linux support from the PS3. Hotz was not even the first to do a hypervisor exploit he just found a particularly serious exploit.
Getting the Wii to playback DVDs is one example of an interesting application that was possible because of an exploit. The custom bootloaders on the PSP and the ability to store games on sd cards was another interesting thing (Sony eventually copied this.) being able to run Firefox on the PSP was another thing. Being able to play ogg or flac on your PSP is another thing. All possible because of exploits.
There is WiiMPC (Audio player), ftpii (an ftp server program.), WiiRadio (A shout cast client) and others. All possible because of exploits.
