You're not making it look bad :)) They're all oligopolies that use their power to make obscene amounts of money and stifle any innovation that threatens their oligopoly. You want to blame somebody? Blame exactly those actors since it's directly due to them that we even need such a convoluted and horribly expensive alternative. From a strictly technical PoV you could implement micropayments in a week in a garage without any fancy blockchains.

Bitcoin is not destructive compared to fiat currencies. Inflationary monetary policies are now causing a global recession, resulting in insane amount of human suffering. There's also climate catastrophe, wealth inequality, and all kinds of other economic and social issues directly caused by fiat currency. It's time to put stop to destructive fiat currency.
