I'm not a legislator, but I'd like to be able to run an app store of my choosing. I'd like to be able to use my general purpose computing device as a general purpose computer, instead of Apple's business connections deciding who I get to do business with. So far as not implementing features, if the bare tech were exposed, I'm sure people would be very happy to implement it outside of Apple. Just because they perpetuate the platform doesn't mean they should control how I use it. As to implementation (i.e. enforcement), that's just whataboutism because the government is more than capable of regulation.
Mastodon already exists; it's just unpopular outside of small circles. People have already spoken with their time that they prefer hosted, "easy" solutions regardless of the evil they perpetuate (even if this preference is coming from a place of ignorance). The biggest question now is how to popularise it.
Anti-monopoly legislation seems like a good starting place. Game console app stores are, at least in my opinion, equally exploitative, but Apple is one of the most problematic publishers out there. Being able to run whatever software you want on general purpose hardware isn't what this is about (although you should be able to, as the FSF has been saying for years). It's that Apple can't monopolise the market like this, so the government should be able to force them to allow competing app stores.
But the parent comment was about neither genocide nor systemic racism. It was about corruption and how, despite it taking different paths in the US, it's equally reprehensible.
No, technical debt is a very general category that includes deliberate hacks, structural flaws, and small mistake bugs. It's anything that over time will damage the code base, duplications and wrong abstractions being very much included in that
The components in modern electronics are interchangeable and have interfaces about as complex as a gear at worst but usually solderable components. The number of transistors is completely irrelevant because no one is servicing the individual transistors. If a CPU breaks, you replace it.
