Because if you pay with a stolen credit card and use the server to do a bunch of fraud/spamming etc there's nothing but downside for the provider. If they ask you to start out slow, and you establish yourself with them as a good client, then they will give you more freedom.
Why not demand payment with cryptocurrency then?
Because, in the words of the parent, "if you pay with [stolen cryptocurrency] and use the server to do a bunch of fraud/spamming etc there's nothing but downside for the provider"?
Because most cryptocurrency-paying clients are spammers, drug markets, or child pornographers.
And if you only ask for this after denying a fiat payment, then the fraction of those clients who also have cryptocurrency is near zero so it's not worth doing. Corporations won't buy crypto to buy their servers with, because they consider it a high risk.
And you still have to give back the crypto if a court finds it was stolen.
