It concerns me. I've no intention of granting them rights to my images other than to redisplay them on a screen in my profile. But also i worked in copyright licensing and I have a good understanding of just what rights they asked for originally. I got until January and then we'll see if they make alter their tos to not try and grab rights i'm not going to give them. Dropbox actually did the same last year, got the same flack and went back and changed their TOS to remove very similar language. But that was 4 days later and by then i'd deleted all my writings stored there.
