Susan Wojcicki, the CEO of YouTube, sat down the The Guardian last week to pontificate about where the “line of free speech” is and how she is the right person to make that call. The great irony here is that Susan gets it. She knows she can’t outsmart the trolls. She knows she can’t fully police them. The more rules YouTube puts out, the more creators adapt and learn to walk right up to the line or on the line itself, maybe even testing what happens when they step over it.
