Russians are somewhat shut off from the Internet and HN is blocked there as far as I know. And although polls say they support the war, it seems more like passive support/apathy than an active support of their government.
On the other hand, Israel does not significantly censor the Internet and the Israeli citizens largely support their government, so it makes sense they influence the rankings disproportionately compared to Russians.

Most people don't like seeing their employment, the stock they hold or their retirement plans stained by this kind of shit hitting the fan. It's one thing to let some token CEO boogeyman catch some flak every now and then, and another thing to be made aware of your own complicity by holding MSFT or HPQ or whatever.
