Microsoft Requested Urgent support on a bug from FFmpeg.
We cannot tell volunteers to not do something (i.e help Microsoft) in the same way we cannot tell volunteers to do something.
And if FFmpeg was so passionate to get a support contract from Microsoft, that should have been a requirement first before they provided the support.
Once again, FFmpeg set their own rules. First with free software and now with free support.
Life lesson: Don’t provide free software and free support, and then complain about your own doing.
