...unless those links lead to their own billing system, which charges a hefty commission.
The policy doesn't seem to make any difference between "in-app-payment" and donations (to FOSS software, at that) except if the donation is for a non-profit (i.e. tax-excempt) organization. StreetComplete has been displaying links to Patreon, Liberapay and Github Sponsors in-app, so I'll have to remove this.
Furthermore, it was rejected because they write I need to supply login credentials for them. I.e., login credentials for an openstreetmap account. It's a bit absurd, would they request login credentials for an email client too? Or an app that enables you to connect with your google account?
