TL;DR: looks like the raw data will be publicly available. Charts made using the raw data will probably be licensed or offered via subscription according to existing business models? ----- The FAQ page says: Where will all the data be stored? This critical function will be performed by the IHO Data Center for Digital Bathymetry (IHO DCDB), hosted by the National Centers for Environmental Information (NCEI), Boulder, Colorado, USA, which is the recognized IHO repository for all deep ocean bathymetric data (deeper than 100m) collected by hydrographic, oceanographic and other vessels. Seabed 2030 will maintain strong working relationships with the IHO DCDB and recommend it to potential data contributors. ----- and the IHO DCDB page says: The International Hydrographic Organization Data Centre for Digital Bathymetry (IHO DCDB) was established in 1990 to steward the worldwide collection of bathymetric data. The Centre archives and shares, freely and without restrictions, depth data contributed by mariners. The DCDB contains oceanic soundings acquired by hydrographic, oceanographic and other vessels during surveys or while on passage. Data are publically available and used for the production of improved and more comprehensive bathymetric maps and grids, particularly in support of the GEBCO Ocean Mapping Programme.
