“Teck points us to the troubling news of Dropbox seeking to kill off an open source project through questionable means, involving DMCA notices. As you may have heard, Dropbox got into a bit of a security/privacy kerfuffle lately after some researchers questioned the news that it uses a hash function to deduplicate files on its servers. If you don’t know, Dropbox is a cloud storage system that’s pretty useful. However, one of the ways it attempted to save some costs was that if you sought to upload a file that was identical to a file on someone else’s shared server, it wouldn’t actually “upload” your file, but just point you to the single file. There were clear security and privacy questions about this.”
