You can't really see Apple as a reference, because of two reasons: 1. they use old data (different license, cc-by-sa2.0 instead of the now current ODbL) 2. they do it wrong (IMHO, IANAL, TINLA) as they don't say which parts are from OSM, from when exactly they are, so you cc-by-sa cannot come to execution and they don't say the data is cc-by-sa and they omit the © icon they use for other data providers (it is IMHO unclear from their credits page if there is copyright on OSM data and what is the license). I think License Working Groups is still working on this to get the attribution right in this case, even if the last few LWG minutes don't seem to trace this issue any more. /rant/ Apparently, if you are big enough and not interested in playing nice, there don't seem to be limits for commercial users to do whatever with osm data - you have to fear nothing (apparently), at least as long as you use cc-by-sa data. (Of course every single contributor might bring you to court, but that is a different story and not very likely neither if you are big enough). /rant off/ cheers, Martin
