changing and ditching their greed

No they won’t because while they of course are greedy, it’s not really greed which is fueling that on the systemic level, but the inherent capitalism mechanism to concentrate capital. Companies compete and that competition ultimately leads to either monopoly or formation of cartel, the ones with more profits are the winners and the losers get eliminated from the market.

What they will do, is to hire more bodyguards, isolate themselves from society even more and fund more propaganda like the article in topic.

The only thing that can change things, as proven historically, is not adventurism (however cool is to dish at least minuscule part of overdue justice) nor the spontaneous outrage, but the organized workers power threatening the capitalist class and their government servants.
