John Siracusa of Hypercritical has had to cancel and refund all t-shirt preorders due to unauthorised use of what is likely a registered trademark:
I regret to report that the Hypercritical t-shirt has been canceled due to the unauthorized use of an icon from a past version of the Macintosh operating system. All purchases will be refunded in full. This situation is entirely my fault. I’m sorry for disappointing everyone. Thanks to all of you for your support.
This is a shame and I feel bad for John, but it’s been a concern that had played on my mind for the last week or two with the recent t-shirt craze. There are a few sites such as Hypercritical that use Mac icons, classic or OS X, as part of their identity, but at the end of the day these are likely still the copyright and/or trademark of Apple. Using them as a site logo doesn’t tend to pop up on Apple’s legal radar but when it looks like you might be attempting to make some money off Apple’s intellectual propery, that tends to get Apple legal involved.
Update: new t-shirts available.
