> why is it so hard to give money to Mistral?

Maybe your definition of hard is much different than everyone else's...

What digital services do you pay for that don't require sign-up, or an account?

I searched for "Mistral subscription" on Kagi and this was the first link: https://mistral.ai/pricing/

You will not create a user, but want to pay?

There is a subscription in there. I'm paying.

What? It seems very doable for people who are interested in it, are you one of those people? Because it sure seems like you're trying your hardest to not find the answer yourself.
