Technology can have good and bad uses.<p>If they do not make them FOSS in public, then the Conspiracy will invent their own and use it for bad uses only.<p>Furthermore, even if a program is written, you can decide not to use it; that it is written (as FOSS) means that you can read its working, now that someone else wrote about it. You can also execute it on a computer, if that is what is desired. Also, if it is well known enough, then hopefully if someone does use it deceptively against you, then you might be able to guess, or to figure it out (although it might be difficult, at least it might be possible if it is known enough).<p>I have no intention using such a thing, but someone else might figure out uses of it.<p>(For example, maybe there are some uses that can be used with movies, for example, if the original actor has been injured for an extended period of time (including if they are dead) or if they want to make up a picture of someone who does not exist. (Although, they should avoid being deceptive. For example, include in the credits, the mention of using such a thing.) Even if it is considered acceptable though, some people will prefer to make movies without it, and such a thing should be acceptable too anyways.)<p>(I think even in Star Trek, in story, in some episodes they made deepfake movies of someone. And even in Star Trek, both good and bad uses are possible. Or, am I mistaken?)<p>Nevertheless, there may be some dangers involved, but there are potential danger with anything; if you are careful, then you can try to avoid it, hopefully.
