its called "consensus"
i think the OP meant UPGRADES. not critical bug updates
EG the difference between the mandatory segwit UPGRADE ... vs the 0.16.3 critical UPDATE
segwits team of the mandatory game plan due to not getting the amount of votes needed but having private investor $25m contract deadline of november 2017 was just wrong on so many levels. to threaten pools with block rejects and nodes with ip bans if they didnt comply in august
i do find it funny how they are not organising such mandatory node ban ceremony to protect the network, but did so for an upgrade
