Everyone can agree on VLC being the best video player, right? Game developers can agree on it too, since it is a great utility for playing multimedia in games, and/or have a video player included. However, disaster struck; Unity has now banned VLC from the Unity Store, seemingly due to it being under the LGPL license which is a "Violation of section 5.10.4 of the Provider agreement." This is a contridiction however. According to Martin Finkel in the linked article, "Unity itself, both the Editor and the runtime (which means your shipped game) is already using LGPL dependencies! Unity is built on libraries such as Lame, libiconv, libwebsockets and websockify.js (at least)." Unity is swiftly coming to it's demise.

Unity uses the LGPL for parts of their own products. The GPL in most cases only requires that derivative work must also be shipped with the same license. The source code from providers doesn't have to be distributed by unity, it has to be distributed by the provider. In this case that would be videoLAN, which has all their source code on GitHub. You can read the text of the LGPL here, and this is VideoLAN's post about the situation.
That puts things into perspective, thanks!
This is incorrect. The distributor of derivative works in binary form is responsible for providing the source code. They can refer to a server operated by a third party, but if that third party stops providing the source code the distributor remains obligated to ensure that it is still available. The only exception is for binaries which were originally received with a written offer of source code, where the offer can be passed on as-is, but that only applies for "occasional and non-commercial" distribution which wouldn't work here.
