Maybe because Google is actual trash and it went from being the best search engine to being an SEO-infested desert of a search, where your query is interpreted however they want not how you want. Latest example from today - search for "micropython html parser" - 100% of results are about normal python not micropython, with the first 4 results being for generic paid programming courses. It's completely useless as a se…
I just performed that search in Google and the top two results are links to PyPI and Snyk packages for micropython-html.parser. The third result is a link to python.org documentation for html.parser (not micropython). Bing returns the result for PyPI and the one for the non-micropython python.org result. I don't see a big difference here (except maybe me learning about Snyk through google and not Bing?).
It's been publicly known that Google has been bubbling search results for years now, and that one individual's search results have no relation to another's.
