It sounds like it's not compatible with all T-SQL commands and data types. It would be tough to get full feature completeness: Microsoft is constantly adding new stuff in each version, like the ability to run Java stored procedures, R & Python in the database, etc. Open sourcing it would let companies expand it to get specific features coded that they need - that otherwise might not get attention from the general public.
