News is indeed public information, but the version I wrote (and copyrighted) is my property - not the public's.

Second, if soemone grabs the news release and stores it on their HD, I would consider that personal use. But positng it on a medium where you do not know who many eyeballs this is getting - I would hardly consider that personal sharing of info.

Lastly, just because it is not commercial or for-profit, it does not mean you can use copy righted material without permission - for example, the common practice in US colleges of compiling/assembling textbooks from various sources.
