Durov is obviously aware of the problem posed by Google and Apple, which form a “duopoly”.
Durov considers that Apple and Google are much more dangerous than Twitter or Facebook. Because Google and Apple can simply ban applications from their stores. Twitter can “just” ban users.
As such, Durov promptly advises to migrate from iOS to Android. Because even if Android isn’t perfect, at least you can install independent APKs.
Telegram does not intend to comply with the censorship ultimatums of the AppStore and PlayStore. If ever Telegram is removed from these platforms, there will be two solutions:
Telegram will share an “official” APK
Telegram is working on a “browser” version of Telegram… for mobile! That is to say that Telegram will be usable without an application, optimized for phones. Telegram will thus become 100% independent of any store.
