I didn't consider the case where you're not just a consumer. Will they kill your (presumably totally separate and isolated) business account due to a charge-back on your consumer account? How do they even know it's the same person?

Even if so, I'd argue if your business is so utterly dependent on a single company's service, that's a huge risk and you ought to be be taking steps to diversify or self-host some things. We've all read those "Company X changed algorithm Y and my business is over!" stories.

As a pure consumer, I stand by my statement: If you're going to charge back a credit card transaction, you're past the point of ever wanting to do business with them again, so shouldn't care what they do to your account.
