The European Commission wants Apple to continue complying with the DMA by requiring the company to offer more features to third-party makers.

The need to ensure Apple’s business is viable might turn out to be a very big deal. Europe has already fined Apple billions to protect the interests of European firm Spotify. It has clawed back (as Apple sees it) $14 billion in tax money. And yet, at least according to John Gruber, the EU contributes perhaps 7% of Apple’s global revenue.

Apple Inc. has been warned by the European Union to open up its highly guarded iPhone and iPad operating systems to rival technologies, or eventually risk significant fines under its flagship digital antitrust rules.
