Tone complaint, really? You asked for reasons, I gave you reasons, not really my problem that it doesn't meet some arbitrary criteria that you made up or wasn't presented "correctly". You didn't substantiate your own position in any way, other than"nazis could've done it".
I can see you clearly evading, so now on to the next part, care to estimate how many of those leaving Mariupol decided to evacuate to Russian controlled territory?
All territory around Mariupol is controlled by Russians. That's the main issue. Cities that have Ukrainian-controlled access are being evacuated much more successfully. So whatever straw man you're cooking with that, just save your time and drop it.
Plus
2400 dead in Mariupol and more yet uncounted under rubble. Doesn't fit your narrative though, does it. Even though the UN itself says the number could be "considerably higher".
no one who's even partially objective can seriously entertain the idea of Russians trying to harm as many civilians as they can.
No one who's seeing destroyed houses, hospitals, schools, etc could imagine Putin having restraint about civilian causualties but here you are. The relatively low numbers (outside of Mariupol) are more likely related to civilians sheltering and evacuating rather than Russian army having any qualms about killing them.
Another "article" that you'll claim proves Putin is the greatest humanitarian:
