If this company now owns DR DOS, why do they need to do a clean-room reimplementation?

The About page mentions some form of ownership but doesn’t address that.

> …DRI continuing to publish updates until their sale to Novell in 1991. … DR DOS would change hands from Novell to Caldera in 1996, and again from Caldera to DeviceLogics in 2002.

> In 2022, Whitehorn Ltd. Co. acquired DR DOS and began the process of clean-room re-implementing this historically significant operating system.

The front page only mentions a “legally unencumbered” reimplementation but not how their acquisition was encumbered.
