I think one of the contributions that Cofacts people make is that even within people who make like browser extensions, and I will use one very concrete example like Gogolook, which is a local startup, it has this app called Message Checker, and when you install it, I think it's Android only for now, it scans all the push notifications. So it doesn't care whether you use Facebook, LINE, or Instagram, because it works entirely locally, like a spam filter does.
