Just a quick link to my good friend’s blog post about WhatsApp and its changed terms of use, what’s behind it and what alternatives there are. See and decide for yourself whether – like an increasing amount of others – had enough and want to try to move away from WhatsApp, Facebook and its unstoppable data collection. Gathering from my own contacts, I see a large number of people at least installing (maybe even moving to) Signal, so there is hope that a critical number can be reached (you get notified when one of your contacts starts using Signal).
It also seem to have an impact on Facebook/WhatsApp already, as they changed the date by which you had to confirm to the updated terms and conditions from beginning of February to May.
So think about it and decide what’s good for you.
