Currently a big WTF because of https://location.foursquare.com/resources/blog/products/foursquare-open-source-places-a-new-foundational-dataset-for-the-geospatial-community/obviously Foursquare releasing the data is a good thing, but Apache 2.0 is not a data licence and IMNALO it is totally unclear how it should be applied. Not even considering compatibility as an inbound license with other licenses that are typically used for data.

Ping @luis_in_brief in case you've not seen the announcement.
