“I have been advised by someone involved in phone and computer filtering and monitoring programs that people should stay away from WhatsApp – not because of some theory a rebbe or rav came up with, but based on real life experiences.”
The conclusion does not follow from the implied premise. I have no doubt (he wrote sarcastically) that thousands of otherwise entirely innocent people are attracted to a life of crime by Whatsapp. However, I am not making a decision for thousands of people. I am making a decision for myself and my family. I am confident that neither me nor my siblings are in danger of (to use the euphemisms) getting “caught up” in a “web of aveiros” simply because we use the same communication app as other people who have used those apps for wrongful purposes.
