DVD rippers are available to anyone who has some time to browse enough shareware and torrents to find a good (and totally free) software version. Piracy is illegal regardless of whether or not the consumer pays for the ripping software or acquires it through a torrent or shareware site (or friend).
By including a ad-supported Ultimate Version as a free upgrade, at least the artist and developers will be reimbursed for some of their time and intellectual property.
