The particular accusation I was referring to was the one pertaining the mob violence in India, which is a tragedy that was completely orchestrated on whatsapp AFAIK. I'm pretty sure I can find more if I look on the media, more recent also.
The founder of whatsapp quitting does not change anything in the equation.
These are just tools of the trade - which in this case was probably some local politics. Today, when more and more such tools are available with instant communication to a large audience, having an educated opinion and thought about the incoming communication (messages, memes or videos, etc.) is more important. Unfortunately, that is way more easily said than done.
With all the media already causing severe cognitive load, giving a thorough thought to something you come across becomes even more difficult, especially when just reacting to it is so much more simpler.
This applies not only to WhatsApp or FB, but the numerous online platforms that have a wide reach.
Since I may have gone off-topic, I suppose I should end this with a /rant
Some of these things that have occurred could reasonably be argued to be genocide. Calling that ‘local politics’ and minimising FBs role is not the way this should be handled.
The WhatsApp founder quit over differences around privacy / advertising, and WhatsApp is only one part of facebook. Facebook can see everything on facebook itself, and Messenger. In addition, they failed to the data that they do have private. The problem is they are failing on both fronts simultaneously, privacy, and preventing harm on their platform.
If they were only failing on one front, then I would have some sympathy for your position.
