If a company has to release their whole product as open source, they likely can’t make back their investment on development.
This particular case may be cut and dry, but I’ve had ffmpeg come after my company just for having an embedded Linux solution that uses off-the-shelf ffmpeg libraries. They claimed we had to release all of our custom libraries and app source and environment that were in the same product even though they didn’t have a line of ffmpeg code in them. As a small company, we couldn’t afford the litigation, so we just dropped the project.
