Last week at Telegram was intense – we’ve been busy polishing the rough spots in our new iOS app and fighting connection issues with little time left for sleep. Yet, there’s no other company in the world I would rather work at. At Telegram, we have the rare freedom to do what our users expect us to do, standing up for their interests.

The recent exodus of WhatsApp founders is a good example of what you end up with if you sell your company. You can earn some money, but you lose something much more valuable – your integrity and the ability to continue improving the lives of hundreds of millions of people.

Last week, it became known that WhatsApp has had a backdoor for years – anybody you had a video call with could potentially read all your messages. Even if there are no more backdoors left (which seems unlikely), WhatsApp has other flaws which make most of the messages sent via the app accessible to third parties.

In the long run, promises given by corporations like Facebook just don't materialize, because these corporations prioritize maximizing profits over serving their users. And that’s what makes Telegram so different – the only thing that will ever matter to us is your interests.
