> I use Firefox. Windows 7 was out 2 years before the iPad 2 and the latest Firefox supports it.
Microsoft doesn't even support Windows 7 anymore. I wouldn't recommend anyone use an OS that isn't getting security updates.
> But my counter question would rather be: why don't Apple let people write alternative OSes for its hardware then? You can install an up-to-date Linux distribution on computers from the 90s. The iPad is a popular product, I'm sure there would be enough people interested in building a Linux-based OS for it.
I'm not sure if Apple is lifting a finger to help, but https://asahilinux.org is a thing.
I'm less than convinced Linux people want to bother, in large numbers, to install Linux on devices that were insanely RAM-constrained until only very recently, when Apple started putting M1 and M2 chips in its iPads. For all I know, there are additional patent minefields around implementing Linux drivers for iPads' hardware.
The only other thing that I can think of that would incentivize them to actively block alternate-OS development is security. If someone else can install a backdoor host OS and then stick iOS on top of it before selling the phone to you, that's a way to compromise a Real Computer that usually isn't possible with an iOS device.
> The problem is that perfectly good hardware is just getting disposed of instead. An heresy, from an environmental standpoint.
Apple will _happily_ buy old iPads for a pittance (or $0.00) and reuse the gold and aluminum and whatnot in it. Because of that, I'm not quite as moved by the anti-e-waste arguments that pop up in discussions of rapidly-advancing hardware. That said, an iPad 2, which pre-dates Retina support on iPads, is going to be slow and RAM-constrained, and anyone who decides to support hardware that old ten years later is going to be in for a world of hurt.
As an aside, one of the ways in which Apple actually helps its developers is by dropping iOS/iPadOS/watchOS support for old, slower hardware, basically giving developers license to require newer versions of the operating system and/or newer hardware models for newer versions of their apps. I listen to <https://www.relay.fm/radar>, and the sighs of relief that David Smith, the watch-app guy, breathes when the old slow watch model gets phased out are palpable even at 1.3x speed.
