Facebook CEO Mark Zuckerberg just published a lengthy post outlining what he describes as a “privacy-focused” future for his company’s various messaging platforms — Facebook Messenger, Instagram, and WhatsApp — and online communication at large.

The letter is Zuckerberg’s most significant preview of Facebook’s messaging ambitions (and the undertakings necessary to reach them) in years. It touches on encryption, data storage, user safety, and more. Zuckerberg admits that some of these important changes could be several years away, but the ideas he’s promoting will be seen by some as a paradigm shift for a company that has always prioritized connecting people publicly. Note, however, that Zuckerberg is largely addressing messaging; this doesn’t necessarily signal any major changes coming to Facebook’s core service or the feed you see when you open the app.
