Actually, possible amusing story: I lurk on a LUG mailing list in central Florida (GoLugTech), where one of the members posted this in Jan. 2018:
Suggestion: add iCalendar for meetings to golug.org
I knew what he _meant_. He meant that, seeing as he's a frequent user of Google's hosted proprietary service 'Google Calendar', would GoLUG please, for his personal convenience, henceforth maintain an iCalendar dataset, that GoLUG would craft and host entirely within Google's hosted service -- basically asking GoLUG volunteers to do ongoing work to support 'cloud' outsourcing.
But since that's not what he _said_, I somewhat mischievously replied to the letter rather than the spirit of his request, exploring in several postings all current _self-hosted_ Linux software (both proprietary and open source), by which one can create/edit and then SELF-host RFC-5545 iCalendar event files for public / LUG access -- with access mediated by the CalDAV and CardDAV access protocols, for reasons I briefly detail.[1]
Hrm, that might explain why every time I look at "add calendars" to my existing postfix+dovecot stack, there seems to be some missing magic in between "caldav server is installed" and "people with phones can do useful things with it".
From what you say, it sounds like the phones don't actually run caldav clients, they instead just run an http/html client that speaks to some web app at google.com/apple.com, and the web app once used caldav internally?
