Pretty sure there was metadata in there already. Stablediffusion has been saving data into there for awhile now. It's not evil in intent. Just strip it out.

If you're relying on file formats to preserve your privacy you've already lost.

So make sure your image processing pipeline strips out all metadata?

Seems kind of a non-issue and AFAIK most image hosting software and social media already strips out metadata anyway for this reason (I know Discord does, not sure about others)

then don't add that chunk to your files...

or write a tool which strips it... it's an easy format.

feel free to complain, but also take action, or it's all wasted breath and whining. no one wants to hear people describe their problems poorly while also taking zero action to fix those problems.

EXIF is valuable metadata for many use cases. Location data and fingerprinting are absolutely problems and the solution is to strip that information before you post images anywhere. Having it in the spec is a net win for privacy because it provides a standard chunk for it so that tools can universally strip it out.
