On the other side of every "useless war" is the what if question. Killing Hitler before WWII would have been seen as a cruel interference with German sovereignty.

Anyway it would be wise not to tie social network corporate affairs to the war. The two are not linked in a more significant way than a social network in general being linked to such affairs as a media.

Are we going to ignore how Zuckerberg dines with the president, donated a $1M to his inauguration fund, put Trump allies in high positions at Meta, loosened the moderation rules in Trump's favour, and got appointed to the president's Science and Tech Council only a few days ago?

If you are that deeply intertwined you can't claim ignorance and innocense on the inconvenient stuff - like the Iran War.

If you want to stay with WWII metaphors: if you contributed to putting Hitler in power and benefited from Hitler's favors, you were complicit to the Holocaust.
