If you’re about to close your Dropbox account because of this tweet, you may want to hold off.
Dropbox isn’t doing anything wrong (or new for that matter):
The system is neither new, nor sketchy. It’s been in place for years, and it’s about as unsketchy as an anti-copyright infringement system can get. It allows Dropbox to block pre-selected files from being shared from person-to-person (thus keeping Dropbox from getting raided by the Feds), without their anti-infringement system having any idea what most of your files actually are.
I don’t intend on closing my account, after all, sharing copyrighted material isn’t what I use Dropbox for.
I would appreciate a price cut though.
