That does not answer the question "Then why would I trust him with my credit card"?
Yet people in the comments seem a bit offended at the perceived breaking of the unspoken assumption that a service can't exist without a need for customers. Merely asking the question "why should I trust you?" implies that I want you to trust me, which I don't.
I think it's very interesting how deeply culturally embedded the notion that a service wants customers is. It's so ingrained that we even don't believe that something can just exist without wanting us to use it.
To me, this kind of feels like you coming to my house, asking me whether you have some of my dinner, and when I say "yes but you need to pay me for the materials" you ask "why should I trust you with my money?".
By definition, a “service” is to serve. Even if you are the only “customer”, it’s still serving someone. And most people have this notion because most services do, in fact, serve other customers, and that’s their main purpose. Not sure why that’s surprising.
> I don't really care whether you use the site or not, I made it for me and you can use it if you pay for your resources.
Going through the effort to make this a publicly accessible service with copy explaining how to use it and what it costs, implies that you at least care enough to serve other customers to go through the effort to do that much.
It does not need to involve customers or even be a business transaction.
My personal data is worth a lot more to me than credit card details.
You surely aren’t this dense, so I assume you don’t think photos of where you’ve been and who you’re with is personal?
