None of the other blockchain 'fork' examples you allude to are really analogous. Most of them (e.g. Bitcoin gold) are third party forks created by opportunists. Ethereum Classic is very much a special case and also very different as it didn't involve the founder selling out to a competing chain/foundation, but instead actively supporting the non-Classic chain.

Anyway, after the live streem, the lastest is that the token swap is off for now and the existing Steem blockchain will continue as before. I would imagine most fork proposals will accordingly off the table, but who can say going forward. I expect many in the Steem community to remain skeptical of the new corporate overlords (which a blockchain doesn't really have), as well they should.
