Introduction to Signal Private Messenger, Whatsapp & Telegram

What is it going to Magic the answer isn’t too simple Services have different pros and cons with you need to evaluate the WhatsApp was created in 2009 as freeware and it was purchased and it’s one of the most views around the world on a technical level open source signal part suffers from the classic Theatre metadata from their customers it’s wet and to reveal information about church describes metadata like so they know you ring a phone at sex service at 2:24 a.m. and spoke for 18 minutes. Line from the Golden Gate Bridge the Secret Service but they don’t know what was discussed so metadata is very much a concern for WhatsApp they might not know what you’re saying but it’s not difficult to put pieces together to figure it out the other concern is Facebook we all know what that Facebook is one of the world’s largest data collectors and they offer free services because they’re able to use your data for profit WhatsApp is an entirely free without ads which makes people wonder what’s in it for Facebook there’s absolutely zero evidence to accuse Facebook of doing any wrong but it is important to ask questions for why they would offer a secure and private messaging platform for free what is unfortunate it really takes away a large portion of a privacy aspect of using the service especially since they are willing to use it for a group chat with 200 read receipts typing voice and video calls maybe it’s not moving on the telegraph created in 2013 By the same creator of VK and his crew are open source
