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?
