I've had 3 or 4 Meetup groups fold and migrate to Facebook, because Facebook offers basically the same features and some nice extras:

allows private/hidden groups (invite only; Meetup can hide the memberlist and require approval to join but the group existence is still searchable)

free (Meetup currently charges ~$70 for 6 months; source: I'm an organizer for a Meetup group and that's our semi-annual bill. I'm not sure if the scale slides based on membership numbers. I can't find the billing email for the exact number at the moment.)

While I do like Meetup and still use it, using Facebook for small group organization also makes sense.

maybe, but just maybe, paying cash is better than paying with every information available on your phone.

Phone? I didn't mention a phone; both Facebook and Meetup are entirely usable via their websites.

We have about 40-50 active and semi-active members (on Meetup), hold a fundraiser, and yet the organizers still have to chip in to make up the inevitable shortfall.

Whether or not to use Facebook (or Meetup for that matter) is something everybody gets to decide for themselves and preaching about what they should do is silly.

Facebook groups don't require a cellphone. I participate in one (much to my dismay... but that's where the group is...) and I never "Facebook" on my cell phone - messenger, "app," website... none are loaded on my phone or ever used on my phone.
