This all happened thanks to the Viacom lawsuit[1], which forced youtube to be the most pro-recording industry, and anti-consumer popular site ever. Now, an automated bot trolls everyone's videos for any knid of match, and if flagged the video is automatically taken down unless you file an appeal. In other words, guilty until proven innocent. Unless you are a record label, then it's innocent until proven guilty.
Did you miss the Family Guy fiasco[2], where they used a 7 year old video of Nintendo gameplay footage in the show, the bot saw it as "Fox Owned", and had it removed for copyright infringement.
The youtube era you describe was for a few months-years. We've been dealing with the bullshit youtube became EVER SINCE. Forgive me if the complaints of a record company insider (in whatever capacity you may be), falls on deaf ears.
This is reminiscent of Lars Ulrich complaining about Napster and the internet in general. Only even he admitted he was wrong about that.
