0/ I did not expect this result from the poll. It's clear to me that developers leaving doesn't kill a blockchain, it can continue operating without new development indefinitely.
Look at Litecoin for example...

1/ First we have to define blockchain death. My general sense is that if a chain is still producing blocks regularly and effectively protects against double spends (the whole point of a blockchain in the first place) then it is still alive.
2/ I think exchanges delisting would effectively kill a Proof of Work chain because no liquidity means no large scale mining. No miner would burn a bunch of electricity if there isn't sufficient liquidity to cover their costs.
Hobbyist miners are by definition small scale.

3/ So what would cause exchanges to delist an asset? Simply put, if they aren't making enough money from trading that asset, they will delist.
51% attacks against exchanges are the most likely reason for an exchange to delist an asset. Eg: the ongoing $etc situation.

4/ 51% attacks are the best way to kill a Proof of Work blockchain.
51% attack against an exchange --> exchange loses money & delists asset if trading fees are less than capital lost --> miners stop mining --> difficulty drops --> no double spend protection --> chain is ded

5/ I expect that we will finally start to see some larger chain deaths due to 51% attacks & exchange delistings in this bear market. Just like a forest fire, burning away the dead wood makes space for new growth and is ultimately what is best for the ecosystem.
