Just read this report <https://www.tomshardware.com/software/chinese-semiconductor-outfit-has-linux-mpp-repository-on-github-disabled-after-a-dmca-takedown-request-ffmpeg-team-accuses-it-of-using-libavcodec-code-without-attribution> about a DMCA takedown on a GitHub repository belonging to Rockchip. The copyright takedown was requested by the FFmpeg project. Their code is open source, of course. As is the code in the Rockchip repository. But the company took their code, removed the original attribution and licensing (LGPL), and put the result under an Apache licence, which is not compatible with the LGPL. Given that LGPL is a copyleft licence, and Apache is not, this could lead others to believe they could in turn take the Rockchip version of the code and develop it further and incorporate it into proprietary products without making any source available -- which is something copyleft is designed to prevent. Of course this action did not come out of the blue. The FFmpeg project had raised the issue with Rockchip back in 2024, but in the absence of any progress since that time, they felt that action had to be taken.
