But I think it's also true that people are more than capable of adapting to such landscapes because we already do that with our desktop/laptop computers. Yes, malware exists and people do get their computers infected. But I believe the reliance of a sort of "watchful eye" also makes us lazy.
I mean, the ideal situation is not one where Apple doesn't have an app store. But imo more like what Google does with android where you can install anything if you really want.
I think the cuts these companies take from having a curated store is too high though. And in the case of apple there's simply no alternative (well, there's the nascent stage of an alternative forming in Europe I guess).
