I kind of get both sides. They shouldn’t scan personal files at all but then again Dropbox files are also shareable and is kind of like YouTube in that way. So if in this case a guy has copyrighted content, which they own the copyright for, and are sharing copies of copyrighted content, how can an algorithm know it’s not some random person. It’s much more likely not to be the copyright owner than to be it. What’s the worst part imo is that there’s no recourse, no appeal process, no one to talk to for the mistake - except it seems via twitter.
