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).
No since I don’t use Windows.
I had the same experience with /r/winstupidprizes recently. There was some post were someone just did something dangerous but nothing bad happened at all. Not even a little bit. It was upvoted thousands of times, had a ton of comments, and only a few of them were calling out how it didn’t make any sense why it was getting upvoted at all.
I wonder how many were bots vs stupid people.
It might be interesting to see if we could create “honeypot” posts like this which are super stupid and outside of the point of the community, then just keep track of the accounts which upvoted them.
AFAIK that would mean ChatGPT and each website (not Firefox) would decide that itself. Firefox doesn’t do it since a website may need it.
It wouldn’t need to be proprietary. The logic could just be “remove everything”. Not sure how the Google Inc thing appeared.
