I'm not sure how much money they'll actually get from this.

The (50,000 employee) company I worked for had very slow IT processes at the time, but when the licensing changed they treated it like a critical security vulnerability because of the amount of money involved: they very quickly migrated their software packages to include non-Oracle OpenJDK builds & rolled out an update to uninstall Oracle java from all PCs. And all server owners were given a deadline to migrate or start paying recovery costs.

I imagined it'd be smaller organisations which would've sat on this issue.
