They are trying to make the argument that is parodied in this meme: https://knowyourmeme.com/memes/we-should-improve-society-som...

I think they're trying to convey "don't throw stones at glass houses." It sounds like they're trying to make the argument that if you're not practicing what you're preaching then you shouldn't preach. Not saying I agree with the sentiment; but I think that's what they're going for.

The reality is that you can have it both ways. I own an iPhone, I know how to build a computer, I buy software, and I know how to code. There is value in understanding how the things you have work, but that doesn't mean that you can't or shouldn't buy a high quality product just because you can't take it apart.

The comment I responded to implies a lack of availability of repairable devices. I'm trying to make the point that the market does in fact offer them, but that consumer choice is overwhelmingly in favour of locked-down shiny things -- leading to wild proliferation of the latter. This preference is so strong that even those who complain about the lack of repairability choose locked-down-and-shiny over repairability, perhaps without even consciously realising it.

It's tiring to read again and again about evil external forces wrecking the world, when the choices are our own, and right in front of our faces.
