Apple has an enormous global footprint. Their devices are made in China, India, and Vietnam, and source parts from basically everywhere. More than half of Apple's revenue comes from outside the US and there are 1.5 billion iPhones in use across the world (somewhat larger than the population of the US).
If you live in Europe you should care for the EU: not only it's the reason why there hasn't been a war for 80+ years, but if we can have a voice on the international stage it's because we are united instead of 27 small independent countries.
Not all Kindles can be jailbroken. It's a constant cat and mouse game, and if you get a Kindle with up-to-date firmware, there's a good chance you cannot jailbreak it for now. Once jailbroken, you need to make sure it doesn't auto-update the firmware. And personally, I think one should rather support open devices. Even if Amazon loses money on a jailbroken Kindle (which I doubt), in the end, it still hurts open alternatives.
Because you still paid Bezos and then have a bunch of extra work to do to not make it a strictly interior to a Kobo. Tailscale+Koreader+Kavita on my Kobo Libra Color gives me access to my entire library at all times from anywhere. I read a lot more now after getting one.
The best managers of my career have all been developers, and like myself enjoy going up and down the management chain based on the need of the org. My favourite, at age 61 joined a ~250 person company as CTO, but spent his initial, transitional period of 90 days, as a part developer, part meeting listener, quietly learning as one would expect, helping them scale to 800+ people.
He's the example to me, of the career I'm intentionally pursuing. There's tremendous amounts to learn from, and contribute to, everywhere. Sometimes an organization and I best work together with me managing, other times with fingers on the keyboard. Sometimes, there are multiple jobs.
We could recognize that we're in a different era, or at least that's my bias. Roles are increasingly combinations of generalists, especially in the AI era.
