A true shame since Telegram is just as centralized as WhatsApp, minus the strong end-to-end encryption. Should it become the de facto messaging app for Brazilians, the next judge will just block Telegram instead.
But decentralized communication networks that work mobile first are hard, we all know it, so there's room for improvement, randomizing server addresses on a daily rotation, or whatever may render pointless these blockades.
Too bad they're switching to a messenger that can easily be subverted by governments and doesn't come with E2E encryption by default. Might as well use Hangouts or Skype.
I prefer open source software that lacks features (e.g. E2E, which could be implemented by someone), than proprietary software that "supposedly" has some features (like E2E) which you cannot verify (that is, Whatsapp says they have that feature, but their software not being opensource cannot guarantee anyone that they are stating the truth).
