We did not originate the Business Source License (BSL/BUSL). It was originally developed by the folks behind MariaDB. Wikipedia has a good article that covers the history: https://en.wikipedia.org/wiki/Business_Source_License

Other large projects using the BSL include CockroachDB and (somewhat infamously) Terraform.

We're very glad to have been using the BSL for Materialize since our very first release. Relicensing an existing open source project under the BSL can be a painful transition.

I was actually asking about the automatic timed re-license to Apache :)

Ah, I misunderstood! Yes, we may have invented that. I whipped up the cron job a few years back in response to concerns from our legal team. I’m not aware of any prior art for automatically advancing the change date for the BSL.
