The programming languages used to build the web often find their way into apps, too. That’s largely due to software that allows developers to “reuse” the code they write for the web in products they build to run on operating systems like Linux, Android, Windows, and macOS.

The Mac App Store has quietly started rejecting apps made with a popular tool called Electron that allows developers to base all of their apps on the web-based code. Some of the most popular apps in the App Store, like Slack, Spotify, Discord, and WhatsApp, fall into this category.
Now it’s unlikely that the thousands of developers who have built their apps using Electron can release updates to them unless the Electron framework releases a major change to its implementation.

Developers could distribute their apps from their own websites, asking users to download them directly. But that means abandoning features like Apple’s auto-update mechanism from the Mac App Store and iCloud sync. And this direct-to-consumer method could soon be locked down, too, with Apple’s controversial notarization requirements potentially requiring their review.

Apple has a history of stunting the web’s progress on its platforms. On iOS, Apple doesn’t allow fully independent third-party browsers, requiring all apps to leverage its Safari browser when rendering web-based content. While browsers like Chrome and Opera are available in the App Store, they must use Apple’s Safari browser behind the scenes to render web pages, rather than their own. That means Apple has a monopoly on how iPhone and iPad users access the web. To push developers toward building native apps on iOS rather than using web technologies, Apple ignores popular parts of the open web specification that other browsers implement, to its own benefit.
