That should just be illegal. The right to measure or to publish things is not about their software, it's a personal right, so Obstacle shouldn't be able to remove your right in their license agreement.
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.
That's like selling or renting you a car and disallowing you from saying bad things about it, or to tell others the horsepower or max speed.
