Macgillivray's resume is extensive: he steered the Google Books settlement with publishers, which if approved by a federal judge could pave the way for Google to scan and index millions of books. He also handled Google's conflict with the Associated Press and defended YouTube against Viacom's lawsuit.
Few Legal Issues
And yet Twitter's legal issues have not been extensive: with the exception of recently-dropped La Russa case, in which the baseball manager was angered by someone impersonating him on the site, Twitter hasn't found itself in legal trouble. That issue has already been tackled with Verified Accounts, and while a few disputes could still occur over Twitter name-squatting (as big brands hop onto the site and find their trademarks taken), it's hard to see a major legal challenge on the horizon.
