Apple has acknowledged the recent terrorism attacks in Paris with a commemorative ribbon on the Apple France homepage, www.apple.com/fr. The black ribbon is a sign of remembrance and mourning; Google has also added the symbol to its homepage in response to the attacks.
In addition, Apple has been contacting affected employees in French Apple retail stores to check they are safe.
Google has made calls to France via its Hangouts service temporarily free. Callers can use the Hangouts app on Android, iOS, and the web to place calls to the country without incurring the normal international charges. The Google+ post making the announcement did not specify any particular countries, so presumably free calls are available from any location where Hangouts can be used. It’s not clear if Google Voice users are also being given free calls.
Note that Skype has joined the team also with free calls to France.
