I'd have to see the actual proposed legislation.
I'm against piracy of owned materials. Copying games, cds, etc because you don't want to pay for them is the same as stealing to me.
Using someone's song in a youtube video that you make no money from doesn't seem like it should be considered piracy. But then, it's not MY song, so who am I to say it's okay to use it? I think that the individual artists should be able to raise a fuss if it's their materials being used. Generally on YouTube if someone uses a song that the artist fusses over, YouTube will remove the audio from the video. So why shoudl there be additional legislation to 'regulate' that?
So it all depends on what the legislation actually states. Does it say you can't use owned materials? Or does it say "we can remove whateve we want"? If I make a video of me handling a python and I'm wearing one of a band's shirts, should I get tagged with "piracy" because I don't own the band? Would that be covered?
It seems there's tons of opinions on what the legislation will entail with no real facts presented to support the opinions.
