The Architecture Apple and Google Didn't Anticipate
WeChat, operated by Tencent and reaching over 1.3 billion monthly active users as of figures published in Tencent's 2023 annual report, is not an app in the sense that regulators mean when they write rules about apps. It is a platform nested inside a platform: a runtime environment that hosts miniature applications — mini-programs — which run entirely within WeChat's shell without ever touching the App Store or Google Play. A user can order food, pay a utility bill, hail a taxi, file an insurance claim and renew a medical prescription without leaving a single interface. None of those transactions passes through Apple's or Google's payment infrastructure. None earns either gatekeeper a commission.
The mini-program count crossed four million by 2023 according to Tencent's published developer data, with daily active users of mini-programs exceeding 600 million. These are not links to mobile websites. They are compiled application code — capable of accessing device hardware like cameras and location services — distributed through WeChat's own review pipeline, monetised through Weixin Pay (WeChat Pay), and identified through a user's WeChat account rather than any platform credential Apple or Google issues.
Why Store Rules Stall at the Door
The App Store Review Guidelines ↗ treat an app as a discrete, reviewable artefact. A developer submits a binary; Apple inspects it; if approved, users download it. That model assumes a stable relationship between what is reviewed and what runs. WeChat's mini-program architecture dissolves that assumption: the container app passes review, but the mini-programs inside it are distributed and updated continuously through Tencent's own servers, with Tencent performing the gatekeeping function. Apple and Google review WeChat itself, not the four million programs it carries.
This structural tension has produced intermittent friction. In 2020 the US government's attempted ban would have forced Apple to remove WeChat from the US App Store — a reminder that even the container app is subject to platform control — but a court blocked the order before it took effect. Inside China, however, WeChat's architecture makes the conventional app-store model functionally irrelevant for a vast category of commerce and services. The commission economics that underpin Apple's and Google's businesses simply do not apply to a transaction settled in Weixin Pay.
Architecture in numbers
The Digital Markets Act, which designated Apple and Google as gatekeepers under Article 3, was written to open platforms to competition from third-party distribution. It was not written to address a case where an incumbent's own app contains an alternative distribution layer that the platform operator cannot easily decompose. The DMA's obligations — interoperability, third-party payment access, anti-steering rules — all presuppose that the regulated entity and the distributing entity are distinct. WeChat collapses that distinction.
The Regulatory Questions That Follow
Outside China, the model poses questions regulators have not yet systematically answered. In the European Union, WeChat's monthly active user figures in the region ↗ were not sufficient to trigger DMA gatekeeper designation, which requires 45 million monthly active end users in the EU. Tencent was not among the companies designated. In the United States, the focus has been on TikTok's ownership rather than on the structural questions WeChat's architecture raises about platform authority and commission capture.
The practical consequence is a regulatory gap that runs beneath the current framework. When Apple enforces its anti-steering rules, or when Google collects a commission on in-app purchases, those mechanisms rest on the assumption that transactions flow through identifiable, reviewable apps. A true superapp routes around that assumption not by breaking any rule but by rendering the rule's architecture inapplicable. The regulatory conversation — conducted in Oakland courtrooms, Brussels offices and Seoul legislative chambers — has not yet caught up with the model that roughly one in six people on Earth uses every day.
