The copyright that Oracle has entitles it to offer a license with the conditions it wants. They've had that condition in their license for decades.

You are not forced to accept them.

Back in the late 90s, Oracle RDBMS was the "won't get fired for buying" RDBMS. It's been downhill ever since. Once Postgres got partitions, it was over.

Oracle still had a market for high availability clusters for a while, but the increasing performance of single servers and SANs and finally cloud services made that redundant.

So Oracle have spent the last 20 years being bastards about licensing, squeezing their existing customers while the customers do their best to migrate somewhere else.
