I think the distinction has to be made between the fork on github to prevent them taking the repository private or something like that, and a fork of the actual blockchain.

If it ends up being a token swap on polo, it's just a matter of what they plan to do with the original base chain tokens (burn or dump them). The witnesses just need to keep doing what they are doing. If they burn it for the swap, fabulous! If they decide to dump it on another exchange as 'steem classic', we all take a haircut on the price. My main concern is with the exchanges. Do bittrex and binance support TRX tokens? If not, it might be an easier sell to keep with business as usual. If they convince the other exchanges to support the swap, that's bad news. If it's one thing we would need to do as a community, is convince the exchanges the community doesn't want the swap. But there quite a few cheerleaders thinking that moving over to TRX is the greatest thing ever.
