Maybe so - but about 90% of the world economy competes this way.
People are not stupid.
'Competing on price' is a dumb thing to do in an oligarchy, because it's effectively handing surpluses to another part of the value chain.
Every industry CEO knows how this game is played, and they definitely play it - there's no explicit collusion needed - it just happens naturally when there are 'reasonably intelligent actors acting in self interest within a market oligarchy'.
'Dumping' to exterminate competition is a very common tactic, used throughout history.
It takes a lot of disruption to change institutional dynamics.
I can't speak for the facts in this situation - I have no idea if those allegations are true or not, but they seem reasonable, I wouldn't be surprised if they are valid statements.
"My gut tells me there is more to it than politics and capitalism." - that's usually all it ever is :)
