(1) the story was downranked off the front page because the topic had already been discussed a bunch—for example in these threads, two days earlier:
Amazon's Ring to stop letting police request doorbell video from users - https://news.ycombinator.com/item?id=39119387 - Jan 2024 (141 comments)
Ring steps back from sharing video with police – mostly - https://news.ycombinator.com/item?id=39120892 - Jan 2024 (15 comments)
Culling repetition from the front page is one of the most important things HN's systems need to do. Actually, it's probably the single most important thing. Certainly it's best if we can link to the previous discussions so people can know where to find them—but we can only do that some of the time. Users help out a ton by posting links to earlier threads. Ultimately we need better software support for dealing with this, but that's not done yet.
(2) Your comment https://news.ycombinator.com/item?id=39138481 was flagged by users. We can only guess why users flag things, but in this case I'm pretty sure I know why: comments that do nothing but quote from the article, or try to summarize the article, are considered too formulaic by readers here. If you want to say what you think is important about an article, that's fine, but please do it in your own words and share your own thinking. To simply paste a quote from the article is too superficial. On HN the convention is to assume that readers are smart enough to evaluate an article for themselves.
(3) The reply https://news.ycombinator.com/item?id=39138536, which only said "and?", was definitely an unsubstantive comment that deserved to be flagged (and killed) even more than yours did. The reason it escaped detection was simple, albeit unsatisfying: pure randomness. We don't come close to seeing everything that gets posted here—there's far too much. I've flagged it now.
(I copied this from the parent comment so I can link to it when this comes up in the future).
"Ring will no longer allow police to request users' doorbell camera footage" (npr.org) https://news.ycombinator.com/item?id=39138423
I posted an on-topic supporting quote to explain why this item was newsworthy and got one unhelpful one-word response and my comment got inexplicably flagged (not the commenter) https://news.ycombinator.com/item?id=39138481
How did that slip past detection? How do I get the abusive flag on my comment reversed? This behavior seems to have managed to push an important story off the frontpage quickly. (yes there was a badly-worded dupe headline, but that's a separate thing)
