@finner I think you have a very odd definition of capitalist. I'm not sure but I'm guessing in your definition somebody like Alisher Usmanov or Mikhail Fridman are also capitalists.
They're not.
Capitalists aspire towards a market with competition, where multiple players are forced to compete for the best price/service ratio to acquire and retain customers.
Say a Jeff Bezos actively uses anti-market practices with Amazon that run counter to the foundations of capitalism.
@finner Essential to healthy capitalism (as opposed to some for of Laissez-Faire capitalism that no country is really doing), is authorities regulating the markets, preventing monopolies, ensuring companies don't control access to markets (say through an AppStore or a PlayStore).
The worst offenders in the US in power, say someone like Musk, is completely opposed to this. You could describe them as Laissez-Faire capitalists perhaps. Not many economists in that stream though.
