Deliberately speculating so someone will correct it: I'd guess they'll make a bunch of enterprise tools to do things like: enable access and synch the data in a way which complies with various policy, encrypt/tokenize/hide certain columns etc, monitor queries, ensure data is encrypted at rest, stuff like that.

Assuming the above it true: I'll bet the reason they aren't so loud about exactly what they are doing is they want to get a head start on it. In theory anyone can build this stuff around DuckDB. From a marketing perspective the clever thing to do would be drive up usage of DuckDB while they build out all this functionality and then the minute corporates start seeing problems with their people using it (compliance etc), they have the solutions.
