I could find no reference to ffmpegs AAC on the audiocoding.com website. 
Could you provide the link?

According to:-


"FAAC is based on the original ISO MPEG reference code. The changes to 
this code are licensed under the LGPL license. The original license is 
not compatible with the LGP..."

Since ffmpeg is LGPL I think you can see the issue.

I find that comments by ffmpeg maintainers are rarely garbage, it is 
usually the most technically accurate and they are under no obligation 
to offer advice, so publicly ridiculing them is not likely to work in 
your favour.
