Harry and Meghan are tired of Facebook allowing hate speech, bullying and misinformation to be posted to their platform, just like the rest of us.
According to sources close to the Royal couple, the Sussexes have been privately advocating for the #stophateforprofit campaign, which I first wrote about here.

According to Axios, over the past few weeks, the couple has encouraged CEOs around the world to stand in solidarity with a coalition of civil rights groups, like the NAACP, Color of Change and the Anti-Defamation League, which began urging marketers to stop buying ads on Facebook via the Stop Hate for Campaign two weeks ago.
Verizon, Levis, Dove, Lipton, Unilever, Patagonia, The North Face, Ben & Jerry’s, Coca Cola, and the Hershey Company, have all released statements saying they would halt advertising on the social media site as part of the #StopHateForProfit campaign.
Facebook announced on Friday that they will label any post that violates its policies but that Facebook deems newsworthy enough to remain online. The company lead by Mark Zuckerberg also said they will remove all posts that incite violence or seek to suppress voters.
