GISAID, the Global Initiative on Sharing All Influenza Data, a service hosted and supported by the government of the Federal Republic of Germany stores the most complete and extensive information on the SARS-COV-2 genomes.
Here is one of the many statements that a scientist must accept:
"You may not distribute GISAID data outside the GISAID community, such as by releasing genetic sequences obtained in GISAID in any publication".
GISAID will even relicense data that is already publicly available in GenBank! A publicly available sequence, when obtained from GISAID, will carry a license.
We believe that the data collected from across the world: China, Australia, United States, Iran, Europe with public research-funds should be freely, immediately and readily accessible to all members of the global scientific community.

Here are the relevant statements on how the GISAID data sharing was born:
GISAID's genesis was closely associated with Peter Bogner – a studio executive with a background in creating and licensing media content, and in philanthropic behind‐the‐scenes work for organizations such as the United Nations and UNICEF. Bogner provided the lion's share of funding for setting up GISAID (a low‐mid seven figure sum) and was key to the development of the licensing mechanism that defines the GISAID data sharing policy."
