I like that they are honest about the cost of using the faircode service, right on the frontpage (5% on top of a 2.9% + 30c transaction fee).
I like that they thought about having tools integrated in the ecosystem to allow businesses to easily now what license the deps they're using are on, and how to easily pay for them.
I haven't looked too deep into it, but if it could handle a dual license model as well, then it'd be beyond awesome. I don't want to force companies (even >$1M companies) to pay if they contribute back any improvements they make.
