Simple publishing of your discovery would not necessarily require 
software disclosure.

Qualification for one of the Electronic Frontier Foundation cash awards 
($100,000, $150,000 or $250,000) for discovery of the first prime number 
in specified ranges would require, among other things, "...a description 
of any hardware and software used in the primality test. EFF reserves 
the right to require a more detailed disclosure."  See 
http://www.eff.org/awards/award-prime-rules.html

What is being poached is not the number itself, but the exclusive
Primenet assignment to test that number.

It's not a matter of law; it's a matter of "fair play" or "rules of the 
game".

No.  It's that some people don't have the patience to wait for more than 
a short time when GIMPS progress is close to certain "milestones".  They 
can't forgo jumping in to "bat out of turn", as it were.

No.  That would _not_ be "poaching".  See my earlier posting about
"Poaching -- Definition".

Right now, PrimeNet has no way to enforce time limits on its 
testing assignments.  (That capability is coming in the future.)  George 
Woltman has periodically stepped in to "manually" cancel laggards that 
are unmistakeably not progressing reasonably.

Some impatient individuals can't bring themselves to wait for George's 
actions; they decide to jump in to "poach".

Trouble is, the poachers all-too-often mistakenly target an L-L 
assignment that is actually proceeding reasonably and is not a laggard.
(That's what's happened to me, multiple times!  I've _never_ been 
holding up some "milestone", but the poacher of my assignments never
bothered to determine that, apparently.)  If they'd leave it to George, 
we'd have fewer such mistakes.

That's hardly ever a poacher's motivation.

That's your right.  But just because _you_ choose not to highly value 
the exclusivity of your assignment doesn't mean that _others_ who do 
value that exclusivity highly should not be able to enjoy the benefits 
of unpoached assignments.  But poachers don't ask whether the 
assignment-holder would mind being poached.
