My family name comes from a Christian town in the mountains of Lebanon. I'm positive it was previously on Apple Maps (I've shown it to people before), but now has no label. It still exists on other mapping services and if I search on DuckDuckGo, the top info summary includes an Apple Maps widget with the town. Clicking on it takes me to Apple Maps with the pin in the right place, without a label.

So it's clear that it was there and is no longer there. I'm not making a judgement as to why it's no longer there (the post on X makes an unsubstantiated claim that it's intentional). Could be a bug for all I know. I'm unwilling to make the leap that it's some malicious attempt without actual evidence. I can only verify that it no longer has a label.
