What if (hypothetically) those 'people' are an organization that needs to organize work, and they're using it because they've tried email and other methods for years, and found that those didn't work?

A lot of us use FB for organizing, not just for seeing what our friends ate for dessert last night. It's not reasonable to tell people abandon one channel without suggesting a replacement. You might as well ask people to give up email, or their phone.

How can you be so bad at email that it "doesn't work"?

I'm sorry, but this is ridiculous. We're talking about a company that has knowingly promoted white supremacists groups for the sake of clicks. I think that warrants putting just a little effort into email.

No tool is going to do your job for you. If Facebook succeeded where email failed, it's just because someone wasn't doing their job, not because of some special sauce that Facebook has.

Just curious - how much organizing do you do? Do you host events with any regularity? Do people like to ask a lot of questions about your events or want to share publicly that they're going to them with people? Do people sometimes want to know who is going to your events so that they can choose when not to go because they don't like that person? (And when someone is going so that they can go) Do you have a very active group of people who like to interact with each other in a public forum? Now is that group size beyond 100 people?

You'd be surprised how crap email is for any of that. You'd be surprised how people don't want to have 10 different apps for all the activities and prefer one central source to catch up on everything. Facebook can be very useful.

Zulip, Discord, Slack, Signal groups, mass SMS, just to name the first five that come to mind.
