That's where "if the costs become exorbitant, Amazon is in a better position to improve their own systems to reduce the amount of overages that people run into in practice" comes in.

If starting 1000 instances exceeds your configured budget, they could simply not start them, and shut down whatever number of instances you managed to start as soon as their cost exceeds the budget.

I guess the question is how precise monitoring and reactionary system Amazon wants build for this, for an arguably marginal use case anyway; they do already provide Amazon Budgets for automatic actions when exceeding budgets, but it's quite not as real-time. And then making the niche cases favor the customer is an invitation to abuse.

But least all Amazon accounts are tied to a credit card, so abusing in a scale similar to e.g. the GitHub case is not that easy.
