"debugger vendors in 2047 distributed numbered copies only, and only to officially licensed and bonded programmers." - Richard Stallman, The Right to Read, 1997
I only have Linux PCs (laptops) and servers, 100% of my work and personal stuff is done there (though for work I do need to hop into MS365, Google Workspace, Zoom, etc, hooray for browsers, my final firewall between me and the walled gardens, though we can have a whole discussion on that).
For mobile, we have PostmarketOS, Phosh, Ubuntu Touch. I really must try living in them, is it on me? IDK, our government even has an identity app for iOS and Android. I should not be using it, I should stick to web. But its so much more convenient. I'm just weak, aren't I?
Maybe I should go for Ubuntu touch, with an iPad on the side or something. At least my most personal device is something I control then. Or just keep my Linux laptop handy (or make a cyberdeck!). But I want a computing platform that does not require carrying a bag. It's kinda sad. Even GrapheneOS (one of the most personal and secure mobile computing experiences out there)'s future is in the hands of its greatest adversary, the one that does not want you to have a personal computing experience.
The entire unitized jet engines on Boeing aircraft drops right off and swaps right into another host, sometimes even to different types of aircraft. PCI soundcards come off a i386 PC and go straight into PPC Macs. AR15 pressure bearing parts don't merely interchange between examples from different time and place but its grip and stock mounting patterns are becoming a industry standard of its own. Early Tesla battery packs come apart into bunch of 18650s and could reassemble into new packs(though it's a big no-no due to RUD risks). Meanwhile, Prius power units or front seats are for Prius only; it won't go into dozen different Toyota models, at least without substantial parts changes, modifications, and reconfiguration. Bugatti Veyron uses its own custom tires that aren't even forward or backward compatible with their own successor.
Same for phones: .apk runs everywhere, Linux do not, cameras don't interchange, internal connectors don't fit together, LCDs specific to anything are default unobtainium. microSD cards works on everything, but the moment you look away, Huawei invents a new incompatible format for absolutely no reason. Apple "reinvents everything" every time but internal organizations of components are stable at macroscopic levels for few generations unlike most other manufacturers.
It's openness of PC that is unique and precious, not closed nature of everything else being odd and inconvenient.
I don't really understand what you're talking about here. Android and iOS are American companies. American culture is John Deere locking down their equipment. Anti-consumer laws, pushing IP laws onto the rest of the world by treaty, being overly litigious, these are all American culture. I think the culture you're thinking of is nearly dead in a shell of corporatism.
The PC was a pretty unique event due to a confluence of historical factors that all came together in a certain way. It wasn't the way of things before, and it's been slowly moving away from how it was, and it's not really got anything to do with being American or not.
When Google does it, of course, same apk files and NDK binaries just run on every models of every make as if always worked that way.
American companies appear to be the worst offenders in the world when it comes to breaking compatibility and right to repair, and this isn't to say those anti-consumer changes are okay at all, but I do think the reality is that, you can't break something that never existed, and it exists a lot more commonly in American things than in things from elsewhere.
