I know it’s a popular medium for communication but I hardly thought sensitive material and conversation would occur in this way. It paves the way for a lot of leaky ships then. A mate has maybe 400 groups and trying to monetarise it and the very concerning issues that are uncovered would surely have heads of companies using better and safer means. My friend covers most cities of China and then most subjects of work, leisure and topics of networking, then he virtually has groups for each country. Naturally there is the one on one rather than groups but it seems China has a few million ears listening in full time to protect interests. They’ve also have automated triggers that will curtail certain features you can use according to some of your past activity that they may wish to restrict.
Anyhow, I accept your view, just surprised.
