If I give something to you it's entirelly up to me to decide whether I want you to give me money. If I want to give (for free) and enjoy doing that, please stop saying "take my money", because I don't want it. If I wanted your money I would have said so or at least hinted you. In other words, don't spoil the moment.

On the other hand, may be it's just me being too sentimental... Or may be it's because I grew up in an evironment where not everything was measured by the money, and giving and helping others without expecting to be "paid" was relatively normal.

Except the copyright owners aren't giving anyone anything.

If Disney put up, front-and-center on their website, a download link for Frozen, saying, "It's our gift to you! No strings attached!" then your analogy would work.

When I do a favor or give a gift to someone, I do it out of the kindness of my heart, or because I care about the person I'm doing the favor for. But when I show up to work and perform my duties, I expect to be compensated. Furthermore, even if I _do_ do something out of the kindness of my heart (like staying late to cover an absent employee's shift) I still expect to be compensated.

There's a time and place for volunteer/charity work, and there's a time and place for compensated work. If everyone just did favors for others, there'd be a lot more people who get screwed over (and also less incentive to do very technical work)
