> how can an ongoing dialogue be past tense?

Easy: it can be considered past tense in case "ongoing dialogue" is a corporatespeak for "f..k you". Which I believe is the case here. But that's an opinion.

> Know Your Customer [..] I don't see any issues with that

This might be the case if you're coming from a standpoint I have mentioned: the American one. This is a world view where everybody have physical paper documents proving residence, every labour effort is arranged in a very specific legal framework, every person have an address in a specific format, every person has one of just a few types of ID documents, etc, etc.

Problem is, the world have vast, vast differences in all of the mentioned areas and KYC companies couldn't care less because they are a business and they make money by KYCing as much people as possible for as little spend as possible. Thus they simply ignore any case that's not mainstream no matter how perfectly legal it is.

Being a digital nomad I cannot pass KYC at the vast majority of online services. My passport is under no sanctions, I do have residency in the first world country, etc., but passing KYC at Persona and others is not possible.

Because of the risk profile. The company has no way of knowing whether "find all security vulnerabilities in this code" is a request from a whitehat or a blackhat hacker. The risk of someone using GPT to hack yet another DeFi project for a hundred millions while mentioning OpenAI is higher than perhaps a million user accounts, let alone a single one.
