This "Ukrainian regime" during the time when it allegedly happened (2001 to 2003) was already overthrown by the Orange Revolution in 2004.

It (personified by Yanukovych) then came back, and was again overthrown by another revolution a decade later.

Yanuk currently lives in Moscow if you wonder.

But really it had nothing to do (directly) with any "regime" and was just a typical post-Soviet shit that was widespread in both Russia and Ukraine.

In Russia for example there were tens of thousands of homeless children living in the Metro and the streets just in Moscow (which was the center for them from all around Russia and actually great many of them were from other ex-Soviet countries), of course a plenty of them just simply disappeared and no one around them cared nor even noticed.

In 1999, while crossing Kursky station, I saw three small children sniffing glue there. I started to speak with them, and it turned out they were living in that station. The children told me to come in the evening, because then there would be very many of them. So I went to the station in the evening and I was completely shocked. There were more than fifty children there, some of them very little. I could not comprehend that these children were really not needed by anyone, no one was searching for them, no one cared about them. They just lived in the street – they lived and they died. https://culture.pl/en/article/russias-invisible-children-an-interview-with-hanna-polak
