Apple ( (AAPL) - Get Report) and the company behind Fortnite and in court. The legal battle could change the way all future digital software is distributed.

Managers at Epic Games say they want to undo the 30% fee Apple collects for distributing software. If they’re successful third-party developers could launch independent platforms on top of Apple software.

It’s never going to happen. Buy Apple shares.

To be clear, Fortnite is a proven commodity. The online community now has 350 million active players. Registered users in April spent a collective 3 billion hours inside the Fortnite universe, battling zombies, and each other. The company makes money by selling advertising and hawking virtual trinkets like avatar outfits and extra lives. Epic also builds virtual communities.

Twenty seven million people showed up last June to watch a virtual Travis Scott performance. The 10-minute concert was a kaleidoscope of rap music and color, unmoored from the laws of the physical world. Fortnite cleverly positions Epic at the intersection of pop culture, tech and commerce.

The business end is big.

As part of the ongoing legal battle Epic lawyers disclosed this week that the platform had sales of $5.4 billion in 2018, $3.7 billion a year later, and $5.1 billion during 2020.

Tim Sweeny, chief executive laid out a grand vision for Fortnite where developers and artists could build virtual businesses inside the platform. The roadblock, in his view, was the 30% fee paid to Apple.

There is an obvious problem with this legal strategy: Apple is providing a real service as gatekeeper to its operating system. While Sweeny may gripe about the 30% fee, keeping payment systems and user data secure is ultimately about trust. It’s a big part of the reason people by Apple products. The company is entitled to charge a fee for providing that service.

There is also the problem of consistency. Epic pays the same 30% fee to game console makers Microsoft ( (MSFT) - Get Report) and Sony ( (SONY) - Get Report) even though gameplay on Xbox and Playstation account for a much larger portion of Fortnite sales. Apple lawyers were quick to point Tuesday that out iPhones and iPads made up only 5.5% of 2020 revenues.

It’s nice that Sweeny wants to create a kumbaya platform where creatives and Epic can collaborate to build new online businesses. It doesn’t mean Epic gets to shun Apple rent.

Some investors assume game producers have the power to change and set the rules. They don’t. Ultimately, the real power rests with the platform gatekeepers, like Apple.

The Cupertino, Calif.-based company has a powerful ecosystem with a billion registered devices. It’s hard to overstate the scale of this business. Customers are fiercely loyal and will often buy Apple products regardless of the limitations.

The Macbook was redesigned in 2015. The new format did away with all of the input/out ports that made the laptop so popular with photographers and digital artists. The term dongle life was born because getting media on and off the device often required an adapter that was sold separately. The laptops still sold well. Customers bought dongles.

The Fortnite lawsuit is much like those early Macbooks.

When Epic Games purposefully violated Apple developer policies in August 2020, Fortnite was removed from the mobile App Store. Apple as a business didn’t miss a beat. Sales of iPhones and iPads have not been impacted one iota. Customer adapted.

Apple reported financial results a week ago. Second quarter sales reached a record $89.4 billion, up 54% year-over-year. iPhone sales rose 66% to 47.9 billion in the quarter. Managers said iPad sales grew 79%.

Apple shares have been under pressure since its earnings report. Some of this is fear the business can’t possibly get any better. Another part of the weakness about lawsuits like Epic’s will encourage regulators to chip away at Apple’s dominant position with iPhones and iPads.

It’s a silly fear. The company is providing a legitimate service to its customers they would not trade regardless of inconvenviences. Longer-term investors should use the weakness to buy Apple shares.
