The first thing I thought when I read this article was how raspberry pi’s just make this kind of thing more difficult and annoying compared to a regular normal PC, new (e.g. cheap mini PC) or used (e.g. used business workstation or just a plain desktop PC).
And if you want GPIO pins I’d imagine that a lot of those applications you’d be better served with an ESP32 and that a raspberry pi is essentially overkill for many of those use cases.
The Venn diagram for where the pi makes sense seems smaller than ever these days.

I often us an Arduino plugged onto a spare USB port. There's a whole lot of GPIO pin related projects that suit 5V better than 3.3V, and Arduino IO pins are practically unbreakable compared to ESP32. I've got Arduinos that still work fine after accidentally connecting 12V directly to IO pins. I've has ESP32s (and RasPis) give up the ghost just from looking at the IO pins while thinking about 12V.
You're right that the Venn diagram is smaller than it was 5 years ago, but there are still some folks whose primary concern is electricity usage. Even the pi 5 shines there (as long as you don't need too much compute).
