This is satire:
In their continuing struggle to selflessly save the musicians of the world from penury, all of the leading record company executives have pledged to "stamp out free humming, wherever it may occur".

"For years people have gone about humming their favourite songs whenever it took their fancy. Normally this would be a source of pleasure. But this pleasure came at the expense of lots of hard work from the musicians who are clearly not getting any compensation for this," screamed an indignant Rilary Hosen of the Recording Industry Association of America.

To further prove that the RIAA's motivation is not selfish, she flourished statistics which prove that artists only get about 2.3 per cent of all money that their work generates. "So they really need every penny they can get," sniffled Ms. Hosen through a cascade of tears.
[...]
"I think it is up to the end users of larynxes to prove that they have substantial other non-copyright infringing uses than humming songs for free. Mute people and those with serious throat cancer would be excluded from this new levy," said a salivating Rilary.

Whereas this is a parody. Clear?
