Do "secure" DNS services make sense?

Question

Domain Name System

A large number of different DNS servers have bred on the Internet, some provide protection against phishing and any virus or parental control, the question is, does such a number of different services make sense if, in the end, they can still be easily bypassed by changing dns in the settings?

Answer 1

"Safe" means no paste?)

Answer 2

Personally, I find it useless. And then we see news about various DNS Amplification attacks. Nursery.
You can raise your own DNS.

Answer 3

The service is just designed for the fact that you will change your dns to theirs, and not the reverse behavior.
