Its basically a symptom of them being huge corporations with people in-fighting for top jobs. It seems one route is to create a new mesagging app, the one that “changes everything now”. These apps are pretty low hanging fruit and not as involved as one like google maps or ms excel, which cannot be easily replaced. So person X releases the new app, gets promoted, leaves it behind and of course the “next guy” also wants to leave a mark and therefore creates his own. Its basically a similar reason why a new JS framework gets released every month.
