Would Youtube even exist if it had to have something like Content ID when it first launched? Its existence definitely took advantage of the relative lawlessness of the web back then. Don't see much difference between how Youtube established vs Uber/AirBnB as far as break shit and pay for it later goes.
While many clips were affected by this, you can still (and could always) find almost anything, uploaded pirated, on the first try -- from songs and shows to whole movies. The main exception is for 1-2 very vigilant artists (e.g. can't easily find non-officially uploaded Dylan tracks that are not bootlegs).
