If you give it to Goodwill, they will sell it. You aren't forcing it on another child. Different people have different values.

If that idea offends you, I will say again: I also really like the idea of taking them apart, knowing they are unlikely to get put back together in working order. So if the idea of donating them doesn't work for you, go with that.

Or come up with some other solution. My comment in a forum in no way impels you to do as I said.
