Stop closing Sunrise Calendar

Stop closing Sunrise Calendar

Today Microsoft announce that Sunrise Calendar will quit on Aug 31, 2016.
But one step backward... What is Sunrise Calendar?
Sunrise Calendar is a multi-platform (web,android,iOS e Windows Phone) calendar.
Sunrise allows users to connect with Google Calendar, iCloud calendar and with Exchange Server. The following third-party services feature integration with Sunrise: Foursquare, GitHub, TripIt, Asana, Evernote, Google Tasks, Trello, Songkick, Wunderlist. As a web app, users can sign-in and use Sunrise in a web browser, with no downloads required. Native Sunrise app can also be downloaded for OS X 10.9 and later, iOS 8.0 and later (both iPhone and iPad) as well as Android phones and tablets.In May 2015, Sunrise launched Meet, a keyboard for Android and iOS that lets users select available time slots in their calendar to schedule one-to-ones. (from wikipedia)
Another fabulous feature is that Sunrise Calendar can import all the schedule of your favorite TV show or sport (from F1 to Nascar,MotoGP to SuperBike).
So why Microsoft want to quit Sunrise? Sunrise team said that they worked a lot with Outlook team to implement the same functionality of Sunrise, but so far this isn't the truth.
I want to ask Satya Nadella (CEO Microsoft) and Pierre Valade (CEO Sunrise Calendar) to NOT quit Sunrise as we know now. Please.
Thanks and regards,
Antonio
