Yeah the code being open-source vs closed-source didn't have anything to do with the legal ruling here. The judge claimed that the Apple App Store and the Google Play Store are not competitors (LMFAO), and therefore Google can be held liable even if Apple wasn't. https://www.theverge.com/23959932/epic-v-google-trial-antitr...
(FWIW, the journalist who wrote both articles is ethically barred from reporting on Apple due to his wife being an Apple employee, but still apparently covers Google/Android, so... Take the slant of his coverage with a grain of salt.)
You have two walled gardens and two monopoly-esque distribution platforms within those walls.
Nobody with an iPhone can use Google Play, and nobody with an Android can use the app store.
Which is why disallowing, or hindering, competing app stores within one walled garden is clearly anti-competitive.
It's not reasonable to expect consumers in one ecosystem to completely leave the ecosystem for one specific app, just like it's not reasonable to expect a homeowner to sell their house and move somewhere just so they can pay a lower utility bill.
Is the utility company serving your house a competitor with the utility company across the street if I have to move houses to switch between them?
Yes, if you look at the market as a whole. Clearly not if you use a reasonable interpretation and consider costs of switching.
If Apple and Google are truly providing unique value to developers and consumers, then they have nothing to fear from alternative app stores. Their profits won't be affected.
