Definately not open source, that would require a copyleft sharing license of some sort, maybe more like an undisputed source code dump for some proprietary game or software. But this RNA code dump while viewable is proprietary, cant do much with it.
Worse if they have a patent they could do a SCO manuver and try to kill open mRNA projects by claiming they contained plagiarized(?) proprietary sequences.
Not sure if you can copyright sequences though it would be bad if you could as that lasts like 150 years now(mickey mouse is still locked up from the 1920s), copyright maxes out at 21.
