Developers of apps built with the cross-platform Electron framework say that Apple has started rejecting their applications during its Mac App Store review process, and has threatened cancellation of Apple Developer Accounts for repeated rules violations.

The issue was first raised in August and only affects Electron apps seeking Mac App Store Distribution. The problem received widespread attention following a developer blog post on Sunday.
