Big deal? Well, they actually changed the name of the folder. And now I can't modify it. So yeah, big deal. I have Logic Pro templates that look there. They all broke. It wasn't too bad for me, but imagine if you had scripts or tools or whatever pointing to a file on your FS that happened to be in one of the affected folders. You woke up one morning and they were all broken.
You can't just rename people's files. That's not part of the social contract I have with you, Dropbox.
