But you're just leaving it on the side of the road for some random person to find. So you might get fined for littering or something, but not giving alcohol to minors
Are you serious? Leaving alcohol in a specific, discoverable place for anyone to get and making sure that there's enough stock for everybody
is tantamount to distributing alcohol without a license and to minors. Please don't tell me you think you'd get away with distributing alcohol to random people (potentially children) in court, even if the method of distribution is leaving cases of it outside under a "FREE BOOZE" sign.
And in this case, you have no idea whether it's illegal for the receivers to receive it or not.
It's illegal for you to distribute in the first place, as you do not have a license to do so. Not only does this likely make it illegal, but any decent EULA will
reserve the right to distribute the software, and likely explicitly withhold that privilege from you.
It is not reasonable to expect a package delivery person to know what's in the package they're delivering, or whether or not it is legal. Of course, if they
do know it's illegal, then they're legally obligated to
not deliver it. In the case of distributing software illegally, it's more like not carding for tobacco or alcohol purchases at a store: You generally need to observe a
reasonable level of diligence when it comes to making sure that the recipients of the data have a legal right to it, and you don't have the legal right to be distributing it
in the first place.
