No, that's not at all what it was defined as or what it could be. CSAM is Child Sex Abuse Material. It wasn't going to be memes of winny the pooh like people argued.

That's also not how CSAM matching works. It simply compares hashes of images. If you take a photo of you in your bedroom with a sign saying "fuck the government" it will not match any CSAM database hashes no matter how authoritarian or fascist the government is, because they don't have that same photo in their CSAM databases.

You're doing what the outraged did back then and thinking CSAM scanning is some sort of AI powered image recognition that scans images for specific things. It's not that at all. It is a database of known CSAM images that have been hashed and that have been confirmed by multiple different governments (multiple different ones so one government can't just put an image of their president that they don't like in theirs and then find out who has uploaded that photo. If it only appears in one government CSAM database it will not be checked). It takes your photo, hashes it, and then checks to see if that hash is in the CSAM database. It won't be, ever.

You know what will be in there and matched? If you download child porn that is already out there on the web.
