Well that was quite a huge rabbit hole of a conversation, but something we definately need to consider and address.
The entire reason robbers rob banks is because everybodies money is there. It is an attractive Honey Pot, where the prize is lots of money. Banks are clearly a societal weakness, which has bred security solutions, but these solutions don't prevent bank robberies.
The same goes for centralization of software, it creates an attractive honey pot, where the reward is not money, but fame and chaos. Which is seeming are more valuable to certain segments of society.
We create security solutions, but they don't stop the hacks. This again is a recognizable societal weakness, which we are doing nothing about.
I think that we could easily convince society that diversification is needed for security, and if we could somehow promise interoperability, without an interdependence creating a Honey Pot, society would go along with it.
But as you mention, centralization, like monopolization, makes people rich and powerful. And they are not afraid to use their wealth and power to destroy those who threaten their monopoly.
I am afraid that unless we figure out how to decentralize MicroSoft highly distributed products, the world is doomed.
This CrowdStrike was just a warning tremor, the real earth quake is coming.
