I imagined an hypothetical scenario where there is a massive hack or some sort of a disaster scenario where there are massive losses, and now those same good samaritans that are funding developers start pushing a campaign to engineer a rollback of the blockchain Vitalik style.
You don’t have to worry about this kind of attack. They worst thing these corporations could do is convince Bitcoin Core to argue about every soft fork so that Bitcoin is ossified and cannot scale. Or maybe use Core devs to convince us a certain soft fork is too dangerous, when it’s the only possible way for Bitcoin to globally scale and have truly private transactions.
