You (like quite a few others) didn't read the linked press release which would have been a good prerequisite for joining this conversation. I guess you really just wanted to unload on your least favorite tech company.
I did read the press release, and this seems pretty open.
From https://www.apple.com/newsroom/2025/02/introducing-apple-inv...
"Guests can view and respond to an invitation using the
new iPhone app or on the web without needing an iCloud+
subscription or an Apple Account."
So what's objectionable about this?Your buddy can invite you to a party using this thing and you can RSVP without installing an app or creating an account. That sounds pretty good to me. You have a web browser, right?
Edit: by the way, probably every single phone has builtin interoperable 1 to 1 video calls from the days of 3G. I remember testing them in late 2002 / early 2003. They worked and probably still work unless they retired the standard because everybody is using apps.
