BU nodes go offline. but the diversity of other nodes kept going..
however if everything was just core.. expect another 2013 event.
diversity and more then one codebase is GOOD for the network
It's good for Bitcoin that it splits in to several different mutually incompatible coins? The combined price of the coins would plummet for sure. Noone wants to use multiple currencies that are hardly different, yet still unfungible.
relying on one team that has one king is no better than fiat. and that is bad.
To be fair, it's BU that wants a "president" and a "secretary" of Bitcoin. No joke.

Not true. SegWit requires only a soft fork, meaning that it has stricter rules, not incompatible rules, to the original protocol. That way SegWit transactions are compatible with non-SegWit nodes.
