⚠ Fragmentation & ContagionModerate threat

Regulatory pressure on the App Store is usually discussed as a threat to the commission; a subtler danger is what compliance itself costs and spreads. Apple increasingly must run different rules in different places — one regime in the European Union, another shaped by American courts¹, others taking form in Japan, Korea, Britain, and beyond — and maintaining a platform that behaves differently in each jurisdiction is expensive, complicated, and corrosive to the elegant uniformity that made the store easy to operate and to police. Fragmentation is a cost even when no single rule is fatal, although so far it has not dented demand in the most regulated market: Europe's net sales grew from $101.3 billion to $111.0 billion in fiscal 2025³.

The deeper danger is contagion. Each concession Apple makes in one market becomes a proven template that regulators elsewhere can lift and demand for themselves; the European alternative-store regime², the American steering allowance, a Japanese or Korean payment mandate — each lowers the political cost of the next authority asking for the same. Regulators now openly learn from and coordinate with one another, so a breach that Apple contains economically in one place still hands every other jurisdiction a ready-made blueprint.

There is an odd comfort in the mess: the very fragmentation that raises Apple's costs also lets it contain each concession locally — granting in Europe what it need not grant elsewhere — and its practiced skill at complying with the letter while preserving the substance travels from market to market too. Its enormous scale absorbs the operational cost of running several parallel regimes at once without real strain.

A moderate worry, structural rather than acute. No single fragment topples the toll, but the accumulation of divergent rules steadily raises the cost and complexity of the whole arrangement, and the contagion of precedent means each victory for a regulator anywhere makes the next one, somewhere else, a little easier to win.
