It's therefore really sad that Flickr fails to see the point he has been trying to make in posting pictures by photographer friends who have given him permission to use their pics on his Flickr account. Flickr says that the account should only have his own pics. That's silly: he may not be using Flickr only to showcase his own stuff, as most Flickr users do, but as a tool to collect information (in the form of pictures) about certain events and causes. As long as he has permission to use that information (and he does), Flickr should not be reducing the usefulness of a service he paid for.
For me, the troubling thing here is not just that Flickr has taken some questionable decisions, such as marking pro-Palestinian and pro-separatist Irish murals as "unsafe" (and therefore only viewable with a login) with no reason whatsoever. It's not just that Flickr seems to have arbitrarily selected Hossam's account, where he openly acknowledges and credits photos that are not his, when its millions of users could simply take credit themselves for other people's pictures and get away with it. Its great crime, unpardonable for a US company, is that it has shown very poor customer service in this case. If a customer wants to host his and others' pics - basically wants to have a group account - why shouldn't he? And if that's not possible under Flickr's account rules, then the rules are silly and should be changed, because the customer should always be king.
