Which I would expect Mozilla employees to know about and abide by.
As full disclosure, I've hired Metalab in the past.
P.S. Contrast this with how we collectively reacted when a Microsoft partner ripped off Plurk's design.
Yes, yes it is.
At best, this was a gross and irresponsible move by Mozilla. And if it's not planned to be in the final product, it's also misleading.
It's still irresponsible to use those images and that layout, after rejecting a bid by that design company to create images and layout for the product, even in a mockup.
(They have since made the video "private" on Vimeo, though it is still on all of their promotional material.)
"Wow, the Metalab stuff looks great. Let's ask for a quote!"
[asks for, gets quote]
"Crap. That's way out of our budget. But we do love that style of design."
"Hey, design intern, can you 'shop some of our content into their layout to serve as a functional mockup until we figure out what we're going to do for the real design?"
[intern shops in content, mockup gets posted to wiki, internet drama ensues]
The infraction really seems to be that this is public. Knocking off other sites for purposes of internal mockups and basic functional blocking seems totally sane.
Internal design or not, saying to your hypothetical intern "hey go knock off the design of the company we decided not to hire until we find something else" is whack.
Why do you think its OK?
In my opinion, it will be difficult if not impossible for Mozilla to create a truly original design if they are mocking up with Metalab's work.
Agree to disagree.
That's just common decency in the artistic world.
Unless you're involved somehow, that is.
I think they've had time to give a public apology or at least a simple "we're looking into this issue". I'm disappointed that they haven't done either of those yet.
EDIT: at this point, Mozilla has given a response to MetaLabs that appears to have satisfied them. That's good enough for me.
(BTW what makes you think people are "out of their minds with rage"? Mozilla did something irresponsible, but I'm not going to get angry about it.)
But where's the marketing/seo angle in that?
I actually want Mozilla to steal my content, edit it for me, sexy it up, blog about it, tweet it out, etc. just as long as they send me some Google juice.
Actually the stolen graphics were used in a real product - the marketing. The moment they used these graphics externally to drum up interest they crossed the line.
