As part of my efforts to eliminate both Google and Facebook from my software arsenal due to their proven records of being unsafe, collecting and selling mis-appropriated data, distributing false information (the list goes on and on), I am seriously considering abandoning WhatsApp which is a subsidiary of Facebook. There are many reports available of security breaches.
Before stopping using the service, I shall investigate if there are safe instant messaging services. Important to me are services with servers in Europe and no connection to Facebook or Google.
Boycotting these companies is the best way to have an impact.
