Google: Do what you want with Reader, but don't kill CalDAV
Is there any stated reason for deprecating CalDAV support? I hope the new Calendar API is open enough for platforms like Blackberry, Ubuntu Mobile, Jolla and Firefox OS  etc to tap into.It's increasingly looking like Google is making it hard for other platforms except it's own Android and iOS(can't ignore iOS because of the number of users) to interoperate with its services like Youtube, Gmail, Calendar etc.
