Source First License 1.1: https://gitlab.futo.org/videostreaming/grayjay/-/blob/master/LICENSE.md
This is a non-open source license. They were claiming to be open source at one point, but they’ve listened to the community and stopped claiming they were open source. They are not trying to be Open Source™.
They call themselves “source first”. https://sourcefirst.com/
They’re trying to create a world where developers can make money from writing source first software, where the big tech oligarchy can’t just suck them dry.
Community audits sound great on paper, but it’s something which the FOSS licenses (eg GPL, MIT) also provide. As a practical matter though, auditing has a two-fold objective: 1) identify risks so they can be quantified, and 2) mitigated. For non-commercial users in the community, an audit is high-effort with low-stakes. This license disincentives mitigation even if the audit does turn up something.
For commercial users, auditing is more palatable, being part-and-parcel to risk management. And these commercial operations have the budget to do it, but then this license means the best way to keep improvements out of their nemesis’s hands is to maintain an internal fork that never returns code to the public repo.
All this seems harder than just using MIT code (or even GPL), if such is available. And that’s exactly why I can’t see myself using source-available software in a personal or professional capacity, when there’s a choice in the matter. It seems worse off for everyone except the owner of the public repo.
