What is the buzz in Canada for a replacement service? This was THE hot topic in the office today, because pretty much everyone with a cellphone in Germany uses WhatsApp exclusively. But no one wants their Facebook linked to their text messages, especially not with all the recent NSA/privacy issues. The hot tip in my (software) company is Threema, a local DACH app that features very strong security, but it seems another popular choice is Telegram too. Are any of the bigger contenders (Line, Viber, WeChat) similar to WhatsApp in the sense that you don't need to set up an account and you can just start texting your real-life friends without being interrupted by ads and other bullshit social features?
