Hello WanWizard,
You many times wrote that something is illegal (even though you are not a lawyer) or you said that something smell for you illegal.
So, I think you should be interested with this:
You should know that official youtube plugin available via OpenPLI feed contains and use code youtube-dl.
So, I think you will remove it now because it "smell illegal" or maybe you are a hypocrite...
Regards,
Sam
