Allowing iOS to sideload apps would be a more direct cure for this, because Apple's decisions about what belongs in the App Store wouldn't necessarily translate to decisions about what belongs on the platform. That would solve a fair number of problems for other developers, actually -- and in the long run would probably benefit Apple, too, by virtue of improving the overall health of the iPhone/iPad platform.
If you look at Google right now, their Play Store still has the app available, mostly I believe, because the CCP has little or no leverage over Google to force their hand.
I do agree, tho that allowing side loading apps would also sidestep this issue altogether.
The law suit that resulted in "browser choice" started in 1993 and "browser choice" was started 2010, so this may happen "soon".
Which monopoly breaks up the monopoly upbreakers?
However, I'm not trying to push any political agenda, I just thought it was interesting that this was a good example of tech platforms being too powerful.
