Exactly.  That is all I was trying to do.  Warn people/companies not to use the driver because they may get sued for using it.  As the below Microsoft exFAT licensing page says at the bottom:

<quote>
Please note that open source or other publicly available implementations of exFAT do not include an IP license from Microsoft. For licensing information, please contact IPlicreq@...rosoft.com.

Above is from bottom of:
