Sorry I had linked the wrong link.

It's clear that these features still exist on the ground. Not being public access areas is an invalid reason to remove data from OSM. So this edit is incorrect and damaging to valid OSM data.

The correct way to handle this is to use OSM's tagging system. access=private, or access=no would be appropriate if they are closed to the public. Once this is done, services that do use OSM data will reflect that and specify their access.
