This we should address. Even if it’s just a downloads number, something simple to start with.
I used to use Braintree. They were acquired by PayPal. One time when I had an issue with Braintree account, they suspended my PayPal account with the same email address as Braintree account. They were never connected in any other way. That’s when I switched to Stripe.
I would look around for other non-PayPal options, if possible. Maybe WePay.
(I wish in not so distant future CP directory allowed developers to sell plugins/themes, and keep small % admin fee to help support the project, but that’s a different conversation).
