Stripping metadata is up to the website / app, not the OS. Many apps use metadata, some don’t. If they don’t need the metadata and decide to do the right thing, then they’ll strip it.
Also upload my Android photos to Ente Photos and the metadata is preserved (thankfully).
So… maybe both Firefox and ChatGPT apps stripped the metadata using something proprietary from Google? Because the image I was testing had custom metadata (including a custom “copyright” field value), but a “Google Inc” unexpectedly appeared in the metadata.
