Not in general.

A)
If the invitation in question is addressed to user A (= attendee).
User A has shared the calendar with this invitation to user B.
Then person B must be granted the privilege "Respond To" in order to
accept this invitation.
That is because the user B is responding (= accept/decline) to an event,
that belongs to the other user A.

B)
If user C is invited (= attendee).
Then this invitation will appear in her "personal calendar".
There she can accept/decline as often as she wishes, because this is her
own calendar.
On her own calendar user C has always full control.

No, this has nothing to do with event privacy.
If you set the event on creation to public, confidential or private does
not matter.
As long as you invite someone, she can accept/decline this invitation.

Event privacy only influences the visibility and/or change privileges
you grant directly to your calendar with this event.
As you grant "View Date and Time" to Public events in your calendar, the
person who you granted this permission, can see Date and Time of all
your public events while directly looking at your calendar.
Again, this has nothing to do with invitations.

I once had that, because my session had timed out.
I just had to login to SOGo again.
