Yep, that's true, not fully effective but:

- Nice for TVs and other devices where you can't control the apps

- Or even in phones or tablets, if you don't have root access , you can block lots of ads in browser or even in apps

- Also, you can reduce the quantity of CPU used by ad blockers on your devices (again, essentially, phones and tablets).

- Also nice for visitors in your network ;)
