I think you might not be considering personal bugfixes (X interaction is great for the common denominator, annoying to me), long-term support (I want to use my device securely in 2045), or custom features (I want to be able to do X, but only 0.001% of people care so Apple doesn't). I use Android, so I can't be more specific. I have heard the unverified complaint that Apple sometimes slows down old devices as new ones are released, which would be impossible in FOSS.
Apple is ultimately going to work in their own best interest. Their particular brand aligns that with the consumer fairly well, but there will be disconnects.
I don't really understand this. You plan to single handedly replace the entire OS and security teams to maintain the OS on your phone for a decade? How will you update the kernel when the proprietary driver blobs stop being maintained?
I expect more people than just me are interested in reducing tech turnover or using old tech in the hobbyist space, ie. not single handedly. And yeah, as the sibling says, if we're relying on proprietary drivers, we're not really FOSS- my fantasy world doesn't just apply to Apple.
Yes, it would be very hard. But today it is impossible, so very hard is hardly a complaint you can make in comparison.
No. They want iOS to be open source, because they want to be able to modify a few bits of source code and use their modified OS for their personal use, and then keep pulling updates from upstream forever after that. Like a small fork.
Perhaps the more generous take is that, with FLOSS software, you don't have to go it alone. My Pinephone Pro will not be running security fixes I write myself. But entirely because of its open nature, it doesn't need to - it will continue to recieve updates for years and years. For once, the hardware of a cell phone is likely to die before the software.
If it gets the support of the right people who know how to write such security software and have an interest in maintaining it, sure. But that's the reason many open source initiatives fall short of proprietary. It's either based on the altruistic whims of a few particular talents, or some company is paying to have them maintain it. And we know the latter is fleeting.
The caveat is that sometimes an initiative can be funded by charity or bounty to keep interest, but relying on generosity for 99.99% of projects is a fool's errand.
