The row about purveying fake news may have grabbed the headlines, but the social-media giant has other woes, too, reports The Economist.

1. The share price is falling, due to predictions of slower growth and lower margins.

2. Objections from European data-protection authorities have forced it to pause a controversial user-data merger with WhatsApp, a Facebook-owned messaging service.

3. For the second time in a few weeks, Facebook has had to admit to flaws in the way it measures how ads are faring.

4. And it has reportedly developed a censorship tool to gain re-entry to the Chinese market.

All these matter because of Facebook’s heft: it has nearly 1.8bn monthly users, or about half of the internet’s population. With size comes responsibility, but it is unclear if Mark Zuckerberg fully grasps this. When first asked, the firm’s founder said the idea that fake news had affected America’s election was “pretty crazy”.

5. Actually, it’s not.
