I've enterered a random sample of addresses from this data set into Google for geocoding and ended up with the exact same lat/lon in about half of cases - but I only tested a handful. Of course it is totally possible that a public domain geocoding source is used by both Cybo and Google which would lead to both having the same data without Cybo having copied from Google. As a further explanation to Sean, in case you're not familiar with the legal situation; while deriving "facts" from Google's database and re-using them in your own data set will often not violate copyright (because "facts are free"), it can violate database protection which is a different legal concept that protects a database from repeated extraction even if the individual extracted bits are not copyrighted. This concept doesn't exist in the US to my knowledge, but someone using such a database in, for example, the EU, could be sued by the database owner. That's why OSM must avoid adding location data that has been derived from non-free sources.
