I think they could find funding and use-cases, if they had something like lincensing and terms of use backed into data to track lineage.
E.g. "this columns contains emails" and is revokable. Or when you publish data, "this column needs hashing/anonymizing/...".
And if you track data across versions and can version relations, you can create lineage.
Overall seen many of these lately, waiting for one to really shine. But not because I think it's a grand problem, as I can version my DDL/DML even/code, but I see some need for it because I have a lot of non-tech people working with data throwing it left and right and expecting me to clean up after them.
