The nature of the censorship is that it isn't targeted at who's seeing posts, but rather at the posts themselves. So it's not necessarily the case that the Israelis are treating different countries differently; it could simply be that Egypt, Jordan, and Palestine are all producing the largest amount of content related to the war given their proximity, involvement, and interest in the conflict.
The whole point of Facebook is that your friend network is going to be largely similar to you: that's how they can impute your interests from analyzing the interest of your friend network and then target ads for you. So what most Americans will see will be largely posts by other Americans. Immigrants from Algeria etc. will have overlapping interests and serve as node-points to move posts from one network to another, but still the majority of posts that an American will see, even on a controversial international topic like Israel/Palestine, will be from Americans, and thus largely outside of the Israeli censorship program.
Thus, my point is that your claim of personal experience as an American doesn't really have much bearing on the question of the scale of the censorship here. They are trying to bring to life censorship that is largely happening away from Americans, where Facebook historically doesn't exercise the same levels of care and respect for speech that they do with Americans (see Haugen's Facebook Files leaks).
I've also got to say that this article has apparently been flagged out twice already seems to be in line with the point of the original article. I know from experience that Facebook moderation discussions don't usually attract this level of flagging, so I'm pretty sure that this has to be related to Israel/Palestine, not Facebook.
Have you used Facebook recently? 99% of my posts are from random meme pages and groups; one's own social networks produce very little of the content you see.
