also like, #Mobilizon is a thing.
It's not only FOSS, self-hostable, allows people to check-in anonymously, federates with ActivityPub and is an easy link to send to people, BUT IT HAS MORE FEATURES THAN FACEBOOK EVENTS.
or if you don't want to bother with Mobilizon accounts and groups: #gathio is also FOSS, self-hostable, anonymous, federatable and well-featured.
there's literally no reason to keep send people to Facebook to get event updates nowadays.
