They've even asked a US judge to hold Apple in contempt and put an end to their "sham" compliance.

In September 2021, US District Judge Yvonne Gonzalez Rogers in Oakland, California, allowed developers to provide links and buttons that direct consumers to other ways to pay for digital content.

But Epic reckons Apple is in "blatant violation" of that injunction, despite the Cupertino, California-based company's claim in a 16 January court notice that it had "fully complied."

Epic says Apple has imposed new rules and a new 27-cent fee (that's about €0.25 at the current exchange rate) on developers for some purchases, which together make the links "commercially unusable."

The North Carolina-based developer also says Apple continues to "categorically prohibit" buttons and still bans some apps from telling users they have other purchasing options. It's all a bit of a mess.
