During his time at Meta, Sir Nick established himself not only as a spokesperson but also a bridge between governments, regulators and the tech firm.
As new regulation and legislation began to force social media companies to take more responsibility for the content on their platforms and the consequences of it, that role became crucial.
He oversaw the creation of the Oversight Board, an independent body set up to oversee Meta’s content moderation decisions.
He said recently, however, that the firm’s actions had resulted in some people being “unfairly penalised” on its platforms too often.
Sir Nick has also been open about his views on Trump’s close ally, Elon Musk, describing him as a political puppet master, claiming he has turned X, formerly Twitter, into a “one-man hyper-partisan hobby horse”.
The former Liberal Democrat leader moved to Silicon Valley initially but returned to London in 2022.
He said he was moving on to “new adventures” with “immense gratitude and pride” at what he had been part of.
“My time at the company coincided with a significant resetting of the relationship between ‘big tech’ and the societal pressures manifested in new laws, institutions and norms affecting the sector,” he said.
“I hope I have played some role in seeking to bridge the very different worlds of tech and politics – worlds that will continue to interact in unpredictable ways across the globe.”
