Great article. I would say the trend started in 2018. You may want to take a look at the PolyForm Project that published a menu of source available licenses in 2019-2020, notably the Shield and Perimeter licenses. These, along with Redis, Confluent and Elastic licenses, represent a growing trend in licensing. But they usually are part of an open core model that includes permissively licensed software.
