The point of the service denial is to agitate precisely this kind of reaction from the public with the desire that they revolt against Putin. Of course if they do, many will die or get locked up in a dark cell somewhere up but it will complicate things for Putin.

The other tactic the western powers have is to try and get as many Ukrainian civilians killed as possible for the propaganda effort. This is why they promote lobbing molotovs against tanks etc. Putin desires to kill as few civilians as possible as he can easily win the war. Winning the peace will be more difficult and they need to make it as difficult as possible.
