One concern would be if the link is to pirated content, of course. That can be a problem where some sites are mostly legitimate but contain some pirated content as well.
Another issue is that the Voice editor is designed to mess with proprietary Garmin voice files. The goal is quite innocent but I don't know how Garmin's legal department would feel about people opening up their files and substituting content.
I applaud mrbombastic for being sensitive to such issues and cautious about making the programs and hacked voice files directly available here.
Now that people know of their existance, any decent search engine will find lots of sources for them and tutorials in various languages about how to use them. In just a few minutes I've found multiple sources for the voice file editor, tutorials in English and Spanish and many voices, like the Governator, the Devil, Stewie, Cartman, Sedara (potty mouth) and other languages like Spanish and Malay.
