This has nothing to do with mesira; it has to do with an unlicensed and probably uninsured child care establishment housed in a firetrap. It is a matter of pekuach nefesh for these children.
Having said that; I moved into my house many years ago and was just about the only Yid on the street. Because of its location and convenience, every chaleria in the neighborhood used my street, and in particular in front of my house, as a play ground from early morning into the night. Screaming, cursing, loud radio…all day long. It was unbearable.
After a few years, the street started to turn frum until it was all frum.
Now, when yiddishe kinder run and play and make noise, it’s all music to my ears. I love going to sleep to it on a Shabbos afternoon. Think about it.
