First, you said iPads are the entire market and I just proved that isn’t remotely true, so accept that. Switching up the goalposts to insult people in markets that either don’t have access to iPads or can’t afford them isn’t ok.

Scale of economy isn’t the reason that globally Apple cannot go beyond 40% of that market, it’s a competitive market and Apple would need to sacrifice profit to sell at prices their competitors can to match them at scale. Apple will not be able to meet even their nearest neighbours down from Samsung because they will not scale their soaring profit margin down to match.

If you care the to be honest about subsidies then you may want to ask why Google dominates all Apple products and why Facebook used to - remember when Facebook had its own preferences before being migrated to the app settings? Apple has often subsidised product with brand relationships to certain third-parties to maximise profits.

As to your vague statement about every iPad shitting every competitor that is is bullshit and dismisses all value propositions in favour or brand comfort and some subjective synthetic benchmarks that rarely reflect real world experexperience. In practice I own a really great Lenovo tab that gives better than or equal to current gen iPad Pro experiences for much less. And I get to side load apps and remove bloat and ads at my behest. What do you get on an iPad? Whatever Apple supplies in the AppStore and that’s it. Wipr is ok if you are ok with Safari but you can’t easily or consistently remove ads from other Apps and you can’t recompile them on device to add features or remove other annoying ones. Synthetic benchmarks don’t tell the real story and never have.
