I deleted my comment because I didn’t really care to get into it with the weird custom license, but widely speaking if it’s not distributable without condition, it’s not open source.
EDIT- And it’s okay that it’s “only” source-available, it’s a creator’s choice how their works are used in the world. But I would argue this project license doesn’t fit the spirit of this lemmy community.
Without explicit license? Without contacting the administrator for permission? This is what I mean by conditions. There’s no need to be pedantic, if the software isn’t available for commercial use how can it be open source? I cannot modify this and redistribute or package it without getting in touch with a project representative.
