Reddit alternatives

With new talk about Reddit going public and the awareness that the platform is here to make money in any case, I have been wondering what alternatives there are to Reddit.

I found this thread but it’s a little old now. Is it still representative of the main alternatives?

Particularly with the FOSS and r/privacy community I would have thought there would be some enthusiasm to adopt a FOSS and decentralised (block chain rather than federated?) approach.
