The elephant in the room in the migration away from #Substack is the payments gateway IMHO
Substack uses #Stripe. Move to WordPress? The payments platform is Stripe. The European platform Kessel.media? Stripe. I haven't seen *any* alternative, have you? Please share!
Stripe takes more or less a 5% cut per transaction. It's available in many countries but not all. It requires you have some sort of company or legal entity to receive the money. Not criticising it but, are there other options?
