Looking at that, Google is only allowed to protect its content with database rights for 15 years after publication, with "substantial additions" getting the same 15 years from the moment of their publishing. I bet there is an interesting legal argument in if modifying opening hours or location of a PoI is considered a "substantial addition", because otherwise any PoI (including businesses) added up to July 2011 would be fair game now :). Not that OSM has the financial means to fight off a behemoth like Google.
Tbh, even then, OSM itself states: "The project is not an exercise in copying maps while trying to avoid copyright traps. We create maps without copying at all! That is the challenge we have set for ourselves.", so the point is moot.
I do wish Apple would just incorporate OSM's PoI data. Right now their's is complete garbage compared to Google Maps and OSM, missing vast swathes of info (or being woefully out of date) in almost all cities.

Interesting though that there's this different (15 years) term where normal copyright is just about forever. That's going to come in handy somewhere for datahoarder me I'm sure :D
