And while you have a bit of a point about Oracle being stagnant... Microsoft? They own and develop tons of things. Microsoft isn't just Windows and Office.
I don't think this will be uncovered because you need money to have a voice in this system and as this serves the bigger moneyed interests, anyone who has an incentive to cry foul will find that their cries fall on deaf ears. Also, PR firms will manufacture narratives to spin things to make the people who are complaining seem like a lunatics. They will also gaslight individuals who raise alarms to lower their confidence. In many cases, they can dig up dirt on whistleblowers and have them jailed. In some cases they can manufacture dirt on whilsleblowers (e.g. Julian Assange) to have them jailed to send a message to future whistleblowers. So they can hold the fort for a very long time.
Just wait 10 or 20 years. Watch the system concentrate wealth in fewer and fewer hands and people blame everything under the sun except the design of the system. I think the winner will probably be either Microsoft or Oracle because they are the most corrupt.
Seriously, does Microsoft or Oracle do anything useful these days? No, they just extort money from the government via overpriced proprietary software licenses, lock-ins and contracts obtained through corrupt practices. That's what winners do.
