I'm assuming they were all released previously in some sort of official capacity. There are many on youtube, I'm not sure who released them. Perhaps released as a part of the 9/11 Commission? I'd be interested to know as well.
It's entirely possible his mother released it as a part of history, perhaps for a particular use, but did not intend for its widespread use or without seeking permission? I don't know.
