I'm not going to claim that my experiences here are the norm because I doubt they are, but the primary impact of Facebook previously splitting Messenger off into a separate app (from the native mobile app) in the circle of people I communicate with on Facebook is that we all (organically, without ever really discussing it) just switched back to using olde timey SMS/MMS for things that would have been Facebook messages. Not at all a spiteful/angry decision, just more of a "well, if I have to go out to another app to do this shit, I might as well just use this thing that works with all my friends including the increasing number of them that don't ever login to Facebook anymore".
