Viable business models for B2B businesses that involve charging the price of a fountain soda per month for anything are few and far between. Just charging your card that dollar costs a quarter or two, and sets up expectations that free tiers don't come with. So you may want a $1.75 fully managed PaaS, but it's doubtful anyone wants to sell that to you.
Indeed, which is why they'll probably lose a lot of people.
I'd be happy to put credit onto the account to use the smaller tier, or PayPal it or something, but I'm not paying for a big footprint that I'm not using.
