No he is not there was a misunderstanding about this because of his song  "Don't Download This Song" when asked about it he replid :

"This is meant to sound like '80s charity benefit songs like 'We are the World' and 'Hands Across America' and 'Do They Know It's Christmas?' And this video is by Academy Award-nominated animator Bill Plympton, and the reaction to this song has been very interesting to me, because a lot of people think it's an RIAA-bashing song that's pro-illegal downloading and other people take it unironically and think that I'm actually encouraging people not to download music off the Internet. And the truth of the matter is, my feelings toward the whole topic are somewhat gray, and I think that's actually kind of reflected in the lyrics. And I think both sides of the issue sometimes act hypocritically, and I just wanted to address the whole peer-to-peer downloading situation without taking too hard of a stand on either side."

here is the song lyrics :

Once in a while maybe you will feel the urge
To break international copyright law
By downloading MP3s from file-sharing sites
Like Morpheus or Grokster or Limewire or KaZaA

But deep in your heart you know the guilt would drive you mad
And the shame would leave a permanent scar
'Cause you start out stealing songs and then you're robbing liquor stores
And sellin' crack and runnin' over school kids with your car

So don't download this song
The record store's where you belong
Go and buy the CD like you know that you should
Oh, don't download this song

Oh, you don't wanna mess with the R-I-double-A
They'll sue you if you burn that CD-R
It doesn't matter if you're a grandma or a seven year old girl
They'll treat you like the evil hard-bitten criminal scum you are

So don't download this song
Don't go pirating music all day long
Go and buy the CD like you know that you should
Oh, don't download this song

Don't take away money from artists just like me
How else can I afford another solid gold Hum-Vee
And diamond-studded swimming pools
These things don't grow on trees
So all I ask is, "Everybody, please..."

Don't donwload this song (Don't do it, no, no)
Even Lars Ulrich knows it's wrong (You can just ask him)
Go and buy the CD like you know that you should (You really should)
Oh, don't download this song

Don't donwload this song (Oh please, don't you do it)
Or you might wind up in jail like Tommy Chong (Remember Tommy)
Go and buy the CD (Right now) like you know that you should (Go out and buy it)
Oh, don't download this song

Don't download this song (No, no, no, no, no, no)
You'll burn in hell before too long (and you'll deserve it)
Go and buy the CD (Just buy it) like you know that you should (You cheap bastard)
Oh, don't download this song
