Snowplow makes big changes to its open-source licenses

"Starting January 8, 2024, Snowplow will begin licensing core pipeline components under the Snowplow Limited Use License Agreement (SLULA). This will include Snowplow Collector, Snowplow Enrich, our different loaders and Iglu Server.

You cannot run this software in production in a highly available manner. For current users of Snowplow Open Source Software who want high availability capabilities in production, you must contact Snowplow for a commercial license. However, SLULA does allow you to run highly available development and QA pipelines that are not for production use

You cannot take the Snowplow software and create a product that is competitive with Snowplow."

Looks like https://opensnowcat.io/ is an open source fork of Snowplow to keep it true OSS.
