The only references to software source code that I found in TomTom’s prospectus related to a discussion about copyright protection of source code (as opposed to “object” code, not open source code). I searched via a .pdf “find” and admit that even after apparently illegally obtaining the TomTom prospectus, I did not read it. In fact, TomTom appears very concerned with its intellectual property (IP) rights, particularly patent protection. TomTom’s position would appear to be a no-no among true-believer open source companies (if you believe there is such a thing) and FOSS zealots.
