Data processing tools had a pricing problem. The Big Data Revolution was google and other companies realizing that commodity hardware had gotten so good that you could throw 100x as much compute at a processing job and it would still be cheaper than Oracle, Vertica, Teradata, and SQL Server.

It's a sad dynamic
