Telegram 是如何做到云存储无限制和免费的？

[ludan7h]

1、可以选择永久云端存储；
2、Telegram 免费；

仅仅是因为所有者是超级富豪所以不在乎那点钱，给全世界人民做慈善？
还是这款 IM 工具有其它的盈利方式？

Q: How are you going to make money out of this?

We believe in fast and secure messaging that is also 100% free.

Pavel Durov, who shares our vision, supplied Telegram with a generous donation, so we have quite enough money for the time being. If Telegram runs out, we will introduce non-essential paid options to support the infrastructure and finance developer salaries. But making profits will never be an end-goal for Telegram.
