You missed the "limited" instead of worse.Like I've already pointed out, nobody can claim that the iOS/App Store and Android/Play Store market for smartphones made things worse for consumers OR developers than the Nokia/Blackberry/Palm market for smartphones. So there's nothing in the past for smartphones that the EU can point to that was better. That by itself calls into question the idea of "abuse". The vast majority of consumers would not want to go back to the Nokia E62 versus current iOS or Android smartphones.
And if you compare the mobile market to desktop/laptop, can you realistically make an argument that bargaining power for consumers has "ceased to exist"? For both hardware and software, the mobile market has experienced a significant level of improvement from 2007-2022. Nobody can deny that. It's improved in leaps and bounds. The relative computing power and app sophistication of a 2007-2009 circa iOS/Android phone seems quite primitive now. That's supposed to be representative of dysfunctional market that lacks competition?
A non-competitive market should show clear signs of stagnation where companies can force consumers to continue to pay without offering much of anything that is improved or is even worse than before.
By limiting what can be done, not could be done, Apple, and Google define and place artificial limits on what our devices could really do or be used for. The things devs could do if they were allowed...
For Nokia/Palm/Blackberry, the iPhone was a very different beast. Google was playing major catch-up and we can remember the legal battles where Apple tried to slow (or destroy) Android. N/P/M never were able to come up with a really competing device and they ... died. App developers had nothing to really do with it.
