We're also seeing this play out in real time with Anthropic with their poop-splatter-llm. They've gone through like 4 rug-pulls, and people STILL pay $200/month for it. Every round, their unlimited gets worse and worse, like I outlined above.
Pay as you go is probably the more fair. But SaaS providers reallllllly hate in providing direct and easy to use tools to identify costs, or limit the costs. A storag/backup provider could easily show this. LLM providers could show a near-realtime token utilization.
But no. Dark patterns, rug-pulls, and "i am altering the deal, pray i do not alter it further".
