As it stands the developers don’t appear to have actively refused to provide source code - it might be premature to call them out for breaking the terms of the license.
Edit: My interpretation above appears to be correct in so far as you don’t have to make the source code proactively available (unlike what Video LANs President claimed in the article)
>Moreover, they don’t seem to share the source at all, which is also a violation.”
But there is still the requirement to include the license to inform the user of their rights. Unfortunately the article doesn’t seem to explicitly say whether there’s a licensee tucked into eg the About screen from the screenshot.
IANAL but assuming there is, then the developers here could still be in the clear?
