sent 15 emails over 9 months to the new owner, offering to help or even take over the repo but i had no replies.
Issues and PRs were ignored(you juste have to see the issues section of the report). Rebuilding from scratch was the only way to fix the licensing & continue the project i guess
And what specifically were the licensing issues? workout.lol is MIT from what I can see.
The licensing issue I referred to was about the videos: many of them came from paid/licensed sources
I wanted to move to a more "new", (robust?) and maintainable stack with TypeScript and a SQL-based backend (PostgreSQL)
Copyleft licenses like the GPL come with extra guarantees that do not violate the core guarantees of open source software. Instead, they make them stronger. The 'restrictions' GPL imposes essentially boil down to this: "if you use (parts of) GPL software, you must give your users the same freedoms the GPL guarantees." GPLv3 and AGPL closed up loopholes that allowed people to bypass those clauses.
But in this case the original project used the MIT license, so the only requirement is that it the form includes attribution to the original project.
