The issue is not trusting credit cars, but how you handle suspected fraud.
Google should know that credit cards can get leaked/stolen. Suspending an account without notification is not the right solution. At least give the customer a chance to defend itself, change payment methods or switch to a different platform.
Totally agree. If they don't trust credit cards, they shouldn't keep customers in the dark and then cancel them out of nowhere, they should offer a better alternative. Treating paying customers like that is terrible in every possible way. The mistake is entirely Google's.
I'm never going to blame someone for not trusting credit cards. Only if you don't trust them, you should offer a better alternative.
