Effectively though we didn't want to limit the database usage in anyway except for preventing people from offering a paid-for hosted SurrealDB-as-a-Service. Some database companies offer a 'core' open source database, and then put their enterprise features behind an enterprise license (or close source them completely). We wanted to build in the open, but at the same time it is our intention to offer a cloud database version so that developers can get going really easily in due course. This doesn't mean that developers have to use it though :) !
Let me know if you have any other questions or points!
