And here we see exactly why the Bitcoin experiment was always doomed to fail. Once a lot of money gets involved too many people have different agendas and a consensus/democratic approach will always fail. There is a reason why successful companies such as Amazon, Microsoft, Apple, Tesla etc are not democracies but firmly run by a single individual who forces his vision upon the company.

It is not competition. It is an internal civil war with people trying to promote whichever agenda they stand to profit the most from
Nobody gets killed - its hard competition.
