This is exactly my thought process. Specailized frameworks - like Napster as specifically a song sharing platform in your example was successful because it coupled architecture with a real life usecase. Architect/Engineers see this and think a generic version is far supieror from a mechanical point. On paper, that is true (e.g. scaling or market reach) but it presents a viability-of-use problem that you end up constantly trying to adjust to the massive wide variety of usecases.
