Err, yes, until the surplus kills off all other competition and allows the supplier to jack prices up sky high, or otherwise bend consumers to their will. There's a reason most countries will stop foreign firms from doing this to them.
Its competition of engineers, scientists, and intellectual labor being atrophied due to overuse of LLM.
Pushing costs at 1/100 for 'thinking' gets intellectual labor people hooked and dependent. Then when costs go 300x, leaves people dumber and less capable of doing things on their own.
LLM companies, by not accurately charging for services, are directly dumping on world-level society and devaluing and addicting people to outsource thinking. Thats the problem.
In reality all subsidized and 'free' services do exactly this. LLM token vendors are making a play against human thought.
The dumping -> non-competitive price increases playbook is historically very, very rare, and relies on a monopoly (or in a few cases oligopoly) with large externally-enforced barriers to entry. The oligopoly case is highly unstable and doesn't last, and besides we don't have notable barriers to entry; we have both market competitors and locally-hosted imperfect substitute goods.
There's essentially no reason to believe the dynamic you're predicting could succeed here, because we lack all the conditions that make it more likely to succeed, and it's very rare anyway.
