That article has a lot of details but I've copied the main parts below:
For the readers unaware, we started distributing binaries on the Unity Store for the open-source VLC for Unity integration back in December 2019.
The integration essentially was a bridge between the Unity game engine and the VLC multimedia engine, allowing to build your own media-player based on VLC technology in Unity-based games. Both Unity, through Mono, and LibVLC are highly portable so this is a compelling argument for this cross-platform integration.
This all changed at the end of the summer 2023 when Unity emailed us...
After our assets got removed, previous and new customers started emailing us about the status of VLC for Unity. Are we going to keep maintaining the assets? How to get build updates? etc.
For this reason, we decided to publish a simple Store on the Videolabs website
This way, existing and new customers can still purchase the binaries for the open-source VLC Unity plugin without our presence on the Unity Store.
