Again, with your hypotheticals—when was the last time you needed to do any of that with Postgres or another FOSS DBMS?
For the vast majority of use cases, a FOSS DBMS and a free-as-in-beer DBMS are indistinguishable. If you're in a category where they're not, then don't use Datomic, but this is still far more than a publicity stunt.
We must be working in a different world. In all my career I've not once worked with a serious business that did not have a support contract for their database system open source or not.
Most of those had escrow agreements for central closed source components with vendors in case the vendor went out of business. (obviously only for things perceived as critical and from companies with some perceived risk of failure).
And god knows how many times have I experienced companies biting themselves because they bought into a product that turned out not to deliver what was promised after the contracts were signed.
Free beer binaries are not mutually exclusive of Enterprise support agreements featuring all those things you mentioned above _for people that need that_.
Completely agree. I'm fine with a free beer license. The context of the post is that the binary is licensed using an Open Source license which leads to confusion.
