The Numbers
Fifteen per cent is the whole argument.Which fifteen depends on where the phone is standing.
Apple has charged 30% since 2008 and 15% to small developers since November 2020. Inside the European Union, since 7 March 2024, it also charges €0.50 for an install it does not process. Nowhere else does that fee exist.
Outside the line
The same handset, the same app, the same account. On this side of the border there is one store and one rate.

7 March 2024
A chronological account of what changed on the day the Digital Markets Act's obligations became enforceable, and which gatekeepers had been designated by then.
The Fee Apple Invented
A close reading of Apple's Core Technology Fee — €0.50 per install beyond one million annually — as announced in January 2024, including which developers it applies to, how Apple calculates the threshold, and why the Commission found it inconsistent with the DMA's spirit.
Named a Gatekeeper
How the Commission's gatekeeper designation process works under Article 3 of the DMA, and what obligations attach the moment a company receives one.
AltStore PAL Opened Its Doors
Inside the line
The Digital Markets Act, gatekeeper designations, alternative marketplaces, the Core Technology Fee, and the April 2025 fine — what the EU wrote, what Apple did, and what the Commission did next.

Apple in Contempt
The April 2025 contempt finding against Apple for non-compliance with the anti-steering injunction — what Apple had done, what the court found it was required to do, and the remedies imposed.
Outside the line
Epic v. Apple from the 2021 Oakland ruling to the 2025 contempt finding, Epic v. Google's December 2023 jury verdict and its injunction, the developer class settlements, and the consumer cases.

Three of fiveThe place where all of this is finally settled
One App That Contains the Others
WeChat's superapp architecture — mini-programs, payments, identity — and why it represents a model that neither Apple nor Google's store rules were written to accommodate.
TikTok and the Law That Named It
The Protecting Americans from Foreign Adversary Controlled Applications Act (2024), its timeline, the court challenges ByteDance brought, and where the divestiture process stood as of the most recent published filing.
The Retention Problem
AI assistant apps — ChatGPT, Gemini, Perplexity, Claude — since 2023, with published download and monthly-active-user figures showing a consistent gap between install spikes and sustained engagement.

Twenty-eight pieces, five jurisdictions, and one handset that behaves differently depending on where it is switched on.
