The CIA may just not need that much for 80% of their targets. We aren't talking about top-level security experts. The CIA might use these tools on very low-tech focused threats. The mere fact that they focus on Samsung smart tvs tell us something about their targets. What person serious about security would have a TV that even had a chance of recording their conversations if it was hacked?

For the other 20% of targets who are serious about security (High-level government actors in countries that can invest a lot of money into serious computer security.) The CIA probably has a bunch of high-level tools that were not leaked.
