What makes you think people proposing this aren't on level (or even above) with Erdogan or Lukashenko? At this point they are just better at maintaining a good image. I don't believe you can have good intentions and still want to introduce such level of mass surveillance.
I think that quite a few people in power who are pushing for this kind of stuff genuinely believe that their intentions are good, and that targeting child porn / terrorism / ... makes it justifiable.
But that makes it worse, not better - those who believe in their ideology with such zeal are more likely to push it through to the extremes, no matter what.
