I don't have many unused houses, however my family does have a tiny summer cottage that we don't use in the winter since it's not insulated and so on.

Coming to it in the spring and finding that some kids decided to have a party in there and almost burned it down wasn't exactly a nice feeling. I certainly hope that it doesn't happen to anyone else, including mr Bezos, however much you may disagree with his business practices.

This is a really awful attitude. It's not okay to break into people's stuff, even if he's "mister evil big-corp". Especially since kids having parties tend to leave a horrible mess. Stuff usually gets stolen, too.

There's a deep sense of personal violation that comes from having one's house broken into; while that is probably lesser for people with more than one house, it's still wrong. Most people who support this sort of thing wouldn't loan their houses out for parties, I notice; if one wouldn't lone out his own house, why might he think it better to loan out Mr. Bezos'?

well, so long as they don't mistakenly break into Jeff's actually-occupied house and accidentally traumatize his wife and kids, I suppose he'd be pretty chill about it.
