Since people are showing interest in GitHub Sponsors, I just wanted to mention: The types of services listed in the article likely falls under VAT in specific regions which can be a pain to calculate. That's one of the reasons I'm sticking with Patreon; they handle tax and chargebacks so the fee isn't a big deal. GitHub Sponsors explicitly says the tax is all on you. They don't mention chargebacks in their docs so it's hard to say, if they're processing the payment on their end, I'd guess they handle it.
