I hope this won't make YouTube pull the same stunt in the near future, at least for the smaller channels.
Blame all the fuckwits of the world for uploading yet another "40 hours of black screen with a metal pipe sound randomly through the video" video.
I saw they take in like 4.3PB a day but that post was from years ago so it's probably even more, now.
Also, 4.3PB per day, at today's newegg HDD prices, is about $100k per day or $36.5 million per year. Yeah, you have to consider replication and whatnot, but you get the point-- this is pocket change for Google.
