But Linux distributions still cannot officially use it... sort of?
Samsung added support for exFAT on Linux, in kernel, with one of their tablets. At some point code was leaked on GitHub. At some other point the Software Freedom Conservancy determined certain GPL-dependent modifications were published in binary form alone. Eventually Samsung properly released their source code under the GNU General Public License (GPL).
I am still unclear about how Samsung was allowed to do so, however. Copyright was never the main concern with exFAT but rather the patents Microsoft holds over the file system. The GPL mandates that code it covers must come with a non-exclusive worldwide and royalty-free license for applicable patents except under certain conditions. I would be curious how this license was accomplished unless Microsoft granted Samsung a patent license prior to March 28, 2007 (or some loophole like that).
I understand how people might be sympathetic to Microsoft and others asserting software patents because they are a for-profit business but that does not apply everywhere. You need to be careful when you apply a license to something as upstream as a file system or a kernel as everything downstream relies upon your decision.
Just imagine if you were separated from the contents of your SDXC card because, somehow, this patent found its way into the portfolio of a troll firm?
Current implementations of the file system are in user space until Samsung's in-kernel module. The Software Freedom Conservancy praised Samsung -- not only for their source code contribution -- but also for how open and public their response was.

While the news was enough to bump RIM stocks up somewhat this morning, the deal inked between Microsoft and RIM does not have Microsoft licensing hardware or software to RIM, instead it is the other way around. RIM is licensing the exFAT operating system for use in its phones at an undisclosed price per device. We know that Microsoft has charged $15/device from some other mobile companies; not that they paid it that way, instead it took a court case for Microsoft to get their full price. Where exactly RIM is going to find the resources to pay for this deal is a mystery, the already cash strapped company is currently suffering from their new OSes failure to launch on time. At least their new phones will be using a common format for their flash storage, assuming the company lasts until the BlackBerry 10 can be marketed. More over at The Register.
"Shares of Research in Motion spiked briefly on Tuesday on news that the struggling smartphone maker had signed a new licensing agreement with Microsoft, but investors who hoped the deal meant Redmond would bundle BlackBerry technology with its phones were in for a disappointment."
