Good luck.
It should be an absolute no brainer to protect the species, to not close the book on possibility forever, to not let the species be limited & cajoled by impersonal & vast techno-captial-ocratic enterprises, that will hedge us in. But the short term wins arent super clear. "What is the use case?" "We dont know yet." We might have to enable possibility, act on principle, to find out.
The threat of living in a post science world, where the universe around us is illegibile because we made it that way, where we cannot learn or see or work some of the most important & connective matter around us, seems like it's worth all the cards, is a no brainer to go all-in to defend against. The war against general purpose computing is a slow & creeping infernal damnation.
Android went dark long ago too. All of the open source apps are abandoned and unmaintained replaced by closed source versions. The Play Store takes a 30% cut of things like Apple. Google decides what kind of apps are available on the app store and it closely matches Apple.
Not arguing but rather expanding: You may be thinking "He just ignored sideloading get real" but tell me, are there any porn apps? No there aren't. They have no distribution channel and are banned on 100% of the computing devices people run their lives with which is their phone. "But porn works just fine in the browser" well so does pretty much anything else even on an iPhone so why are we even chatting in this thread? To end users Android sideloading does not exist.
Apple and Google control what types of software humanity gets to use and there are no viable alternatives. Apple has fully embraced 1984 as these recurring threads keep pointing out but Google follows Apple in lock step on nearly every decision. There is no third choice except the increasingly crippled web.
In terms of mainstream stuff, I think that's less of a "Apple & Google don't want you to have them" and more "society doesn't want you to have them, won't somebody please think of the childreeeeen".
Parents ignoring the fact, of course, that the 3 year old they gave a fucking tablet to with unlimited access can still end up on any of those sites via the browser.
This excuse is exhausting, lacks any principles whatsoever; these are general purpose devices, browsing the web & allowing arbitrary apps to be developed & squeezed into the world, if they pass through the tyrant's gauntlet. That one company offers some modicum of un-tyranny is a poor defense for locking down & excluding general purpose computing, for withdrawing the systems we have in our pockets from our own ownership & ability to control.
Citizens should have some options. The implications that althe market is free to do whatever & citizens are free to pick from what's available seems presently somewhat tennable, but if we step back just a little bit here & look at the picture, it's horrifying. The inability to root most Android phones shows that actual freedom, real general purpose computing, is an extremely fine & narrowing little sliver, of the most important & most used general computing world.
