Oh please! You can't honestly believe that Microsoft didn't exert any pressure to get exFAT specified as the filesystem? There was no reason to specify a filesystem in the standard at all. SATA drives don't have a 'specified filesystem' now do they?
But even assuming that Microsoft had nothing to do with exFAT being adopted as the SDXC filesystem (yeah, right) it still relates as MS could have released the exFAT specification and they could have released the filesystem from licensing.
That would have been sign of them being a more open company, allowing integration with other OSs, but instead it just looks like since they failed to kill off OSS, they're now trying to own it. Same old Microsoft.
