The present state doesn't matter much though? At least, doesn't matter much over the trend. There were also many times more BlackBerries in the world than iPhones in 2009, but the trendline was pretty clear to anyone who was watching, and material reality has caught up to that trend as expected, with BlackBerry being firmly dead and buried. FB's products are trending downwards and TikTok is trending upwards. FB has pulled out the stops to stop the slide but has yet to find success doing so. If FB doesn't arrest the slide from relevance it's only a matter of time until TikTok catches it in absolute terms. The salient question isn't whether or not FB is bigger right now (the answer is unequivocally yes) but whether or not they can halt/reverse the decline of their product.
