Founder of secure messaging app Telegram says iOS is stuck in the 'Middle Ages'

In the rant, he criticized the company for a dishonorable business model of "selling overpriced, obsolete hardware to customers locked in their ecosystem", but added that this "obsolete" hardware is not the real problem.

He lashed out at Apple saying that the worst part of the company is that it does not allow users to install apps from other sources than its own App Store and that you cannot use other service than iCloud to back up your device.

Durov is not only a tech founder, but also a strong voice against totalitarian governments. Not least because he himself was a victim of what was effectively a government takeover.

He founded Russian social network VK in the 2000s, and much like Facebook, it quickly grew to millions of users (VK currently has over 100 million users and its popularity is waning). However, in 2014, after years of fighting takeover attempts from billionaires close to Putin, he was forced to sell his stake in VK and eventually fled Russia, effectively surrendering the independence and control over the social network to the Russian Government.
