Kinda reverse meta question here (what?) --
I have been pressured by colleagues/contacts and for ages now to join the whatsapp thing (for professional purpose).
I hate to be in this situation when I feel I'm the one who is right (not giving away my data to cheeky Markus) but I will finally have to give up to my social environment (evolution what?). Just like I finally bought a cell not so many years ago, because I had become too weird to people for not having one (and yeah ... buying a dumbphone nokia hasn't really helped me out, then...)
The point is that I'm being insulated for not being on whatsuck. It is pretty standard in my industry ... so distrubing that many big commodities players are using this app with management (at least implicit) approval to exchange information on markets, deals, etc... (after 2017, I leave it to you to judge whether GS fit in this category of commodities traders).
BTW What shall be my posture please? It would be difficult to convince everyone to move to Telegram or the like.
Any comments welcome. Merci!
