> Replacing all instances of libFFMoeg.so on a drive is not particularly harder than replacing one. but how would you know the new version works with the app? And how do you even know the app needed this library? Are you going to now investigate every app, and check that the library needed updating? It's work, even if each individual app has only a small amount, it will add up. And not to mention _every_ user would need to do it for themselves.
