Artillery and MLRS is being used for that purpose in places where Ukrainian cities are within range. But that does not apply to most of the country.
Given that Russia has openly talked about targeting civilian infrastructure to "freeze them out" (and then tried to pull that off last winter), I think you should be rather careful with your assertions about others' echo chambers...
Yes, Russia army attacked electric infrastructure, that's common knowledge. No, there is no use of precision weapons to willingly attack apartment houses, that's definitely a lie.
There is a lot of cases of Ukrainian army to use indiscriminate and "dumb" weapons to attack civilian districts of Donetsk (and now, Belgorod) just to terrorize population.
The use is terrorism, of course. Breaking the will of the population is very much a war strategy, and it has been tried before (notably in WW2). If you believe that it is effective, there's no reason why precision weapons can't be used for that purpose if that's the only thing you have that can reach and hit.
And, sure, the Ukrainian attack on Belgorod is similarly problematic. But if you're willing to go there, how many attacks have Russia carried in the same time period?
