Is there any reasonable non-commercial replacement for Meetup on the horizon?

I used to go to some hiking and bike riding meetups years ago, and those types obviously don't end up as sales events, but they still had issues with the weird Meetup system where people "had to" take charge of groups and pay somehow etc.

I remember that every time I had taken part in one of those groups, the next time it was somehow some slightly different variation of the same group under a different name that I had to find using their search. All just for the internal workings and politics of the Meetup system.
