I'm fairly sure Windows does upload at least some hashes if you have it enabled in Windows Defender (which it is by default). Don't expect Ubuntu does this though.

Yeah, Windows Defender does worse if you let it have sample submission on. It'll send binaries to Microsoft and they will run in Azure!

That said, "this has happened forever" is false too. These behaviors are relatively new and relatively under the radar. Many people don't know they exist to get upset about it.

Ubuntu uploads (at least it did couple years ago) your data to Amazon.
