It is only possible because Apache License is a so-called "permissive" license, whereas GPL, CDDL and other "copyleft" licenses will not allow such "source-less Open Source" non-sense:

Esri has participated in the development of national, information community, OGC, and ISO TC 211 standards from the development of the US Spatial Data Transfer Standard in the 1980s through the development of OGC Geopackage today. As a sustaining member of ASPRS and a Principle member of OGC, Esri would gladly participate in efforts to further the development of open LIDAR and point cloud standards. Keep in mind that ASPRS owns and maintains LAS, along with other spatial information standards, and would have the lead in moving it into  OGC or ISO TC211 for further work if they so desired. Esri will continue to support and use the ASPRS LAS standard; the Optimized LAS (see FAQ at https://github.com/Esri/esri-zlas-io-library) is not intended to replace LAS but to enhance access to remotely stored LIDAR information for our users.

The OGC invites interested members who wish to  work on this effort to please contact Scott Simmons (Executive Director, Standards Program  E-mail : ssimmons at opengeospatial.org<mailto:ssimmons at opengeospatial.org>  ) to register their interest and discuss details.  OGC will also be holding an ad hoc session at our next Technical Committee meeting in Boulder, CO, USA in June 1st (more details will be send soon) to bring together all interested from all sectors (government, industry, academia) for this and plan next steps. We welcome feedback and input from Esri and invite them to join this effort to  support open LIDAR formats.

This is of concern since the fragmentation of the LAS format will lead to reduced interoperability between applications and organisations, and introduce vendor lock-in.
