“Developers will need to certify their non-commercial status annually to Apple to keep qualifying for the fee exemption.”
Apple charges €0.50 per first annual install past one million for any developer who wants the sideloading and alternative store rights the DMA forced it to offer. Free apps now escape the fee if their makers certify to Apple every year that they earn nothing. Small developers get a three-year grace period, then a cap of €1 million a year. The law was meant to open the App Store, and Apple still sends the bill.
