That depends on what you think their investors interests are. Facebook is losing a lot of social capital by pursuing the path that it has. I am an investor in Facebook (not one that matters, just have a few shares), and I, out of pure self interest, want them to reform themselves in this regard. Yes, there is a path to short term profits that aggressively exploits clickbait. However, as is becoming apparent, that path is going to lead to heavy handed regulation and/or a mass exodus from their platforms. Either of those things would be disastrous for future profits, so I don't think, even from a purely self-interested perspective, that it's true that they don't want to solve this problem.
