I don't know why this focused on WhatsApp when this is the fundamental problem of free markets - somebody is going to win, and then they're not going to want to give up their top spot, using all sorts of barely-legal tactics to accomplish that goal. Notice I said barely-legal - there lies the answer - the legal system. You're not going to fix dominant players abusing their power with anything but laws and culture that make it untenable to treat people like shit. Now comes the kicker - who is going to make sure the law-makers and law-enforcers don't abuse their power? Where's your 'free software' solution to that dilemma?
