> it can be composted in municipal facilities according to the bag

Note that "according to the bag" is very different from "according to your municipality"; my understanding is that most places actually can't handle them, and they might need to divert your compost to the landfill if it has too much of those plastic bags. They can be composed under certain conditions, but whether the facility your municipality uses has those is unclear.

That really should be prosecuted for false advertising. Just because I can physically flush Orbeez down the toilet doesn't mean it's safe to do so.

I'd assume those bags would be okay considering they break down after a few days of holding compostable materials, and frequently make a mess in the compost bin. The "compostable" cutlery is definitely not compostable under normal household situations though.

My understanding is most manicipal compost facilities can handle them - the vast majority of manicipalities don't have a facility at all. They are expensive. A home pile won't compost them, a pile at manicipal size is likely a health hazzard and so not a good option.
