the way i see it there are 3 types of resellers. the ones using fake credit cards to rack up costs and then cancel the card are doing actual fraud. then you got mass free trial abuse which is more of a gray area and i would say its still wrong. but if you sign up for a subscription, pay for it and resell your monthly tokens thats not at all unethical, even if its breaking their terms and costing the provider money.
imagine ford starts renting out company cars at a huge discount so they can get people to buy the same model for themselves after they drive it at work. its the exact same car and costs the same amount to make, they just take a loss on it and use by anyone other than employees is banned in the contract.
some small company realizes they dont really use their cars that much so they rent them out again for 3 days a week to get some extra cash. is that fraud? it costs ford nothing because they get the same payments either way, they just lose potential profits. they are the ones who decided to set up a loss leader and take the risk of someone "abusing" the system so we dont need to use public resources to defend their strategy. that wastes taxpayer money to protect corporate profits, and it creates moral hazard because ford (anthropic) is not the one paying for enforcement.
Instead of credit card, prepaid stablecoin purchases would solve the problem. No chargebacks.
