I think you raise a valid point and I've seen it multiple times already that links/stories about Israel's crimes tend to be flagged on HN and not shown to most users. I don't have a good explanation.
So are stories about Russian attacks on Ukraine. This one is the exception so far and likely only because it involves a NATO member. And I still wouldn't be surprised if it got flagged.
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.
Tech and the occupation of Palestinian territories have enough overlap to warrant organic self-interested flagging, and that isn't even accounting for any coordinated or state-sponsored activity.
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.
