Just the open is similar, but the intent is totally different, and so is the focus keyword.
Not facing this issue in Bing and other search engines.
Some popular models on Hugging Face never appear in the results, but the sub-pages (discussion, files, quants, etc.) do.
Some Reddit pages show up only in their auto-translated form, and in a language Google has no reason to think I speak. (Maybe there's some deduplication to keep machine translations out of the results, but it's misfiring and discarding the original instead?)
I think at least for Google there are some browser extensions that can remove these results.
It’s also clearly confusing users, as you get replies in a random language, obviously made by people who read an auto translation and thought they were continuing the conversation in their native language.

So, for a topic, if I have two of the above pages, Google will pick one of them canonically despite different keyword focus and intent. And the worst part is that it picks the worst page canonical, i.e., the tag page over blog or blog page over service.
This is what has caused the degradation of search quality since then.
