I'm curious to understand the implications of the AGPL-3.0 license in the context of this project. It sounds like the author doesn't want big corps to offer a hosted version of this tool (because doing that would require them to release the source code of any modifications they make to the software, which many companies are reluctant to do) and it's also an OSI approved license (unlike the recently famous SSPL or BSL). What's so wrong about AGPL-3.0 then?

The intention is often to prevent companies from building proprietary services on top of open source software and I feel AGPL 3.0 is a sensible choice here.
