This right there is the root of the entire problem. We had IBM PC clones that you could recover and keep running for decades by easily replacing expansion cards, HDDs, RAM sticks, peripherals and even circuit components like caps, ICs and batteries. We used to partition our 50 GB HDD into a dozen little partitions and multiboot every conceivable OS out there. Now we have an oligarchic dystopia where even RAMs and batteries are soldered on and bonded with single-use resins instead of age-old screws. Even if you get through, you can't salvage or swap ICs because they're paired individually at device level. You can't reach the boot partition without a Ph.D in RevEng and a risk of still bricking the device 3 out of 4 times. And that's all for technological progress and security, they say! Those claims have as much credibility as their claims to making an honest living. It's weasel-speak, not engineering insight.

Modifying the device that you paid for should never be this complicated. Those greedy corpos are usurping the consumer's rights and wealth, plain and simple.
