That also seems fine, provided you draw the distinction. (I don't claim to be any kind of arbiter of taste, but you asked, so I answered.)

Have you looked through the responses to the meltdown of Celsius on Twitter? In many individual cases these appear to be ordinary people, in shock at having lost practically everything. All I'm saying is that laughing at people like that seems to me to be in very poor taste.

Michael Saylor and his ilk are definitely fair game, though. Just be sure to leave some Schadenfreude for me!
