When Edward Snowden tells you not to download something, it's generally a good idea to heed his advice.
So it's safe to say that the popularity of Google's 'Allo' app is set to suffer after the cyber fugitive tweeted out this warning.
'Allo', for those who don't know, is a smart messaging service in the same vein as Facebook Messenger and WhatsApp.
But it was recently revealed that all chats are stored on Google's servers. It was initially indicated that the messages would only be stored temporarily, but that hasn't proven to be the case.
Google say that they will use the data to improve parts of the app – but it's still a breach of privacy that a lot of users didn't know they were surrendering to.
But then, what haven't you told Google by now? Downloading 'Allo' would be but a breeze in the tornado of indignity that they could inflict on you if they so wished.
