That's not just a dark pattern, it's the logical conclusion to Apple's entire business model. It's what you get for relying on the proprietary OS supplied by a hardware manufacturer. It's why Asahi Linux is so important.
"regularly" is doing a lot of work here. When Linux drops hardware support, we are talking about ancient hardware. An example of a regular drop: Linux 6.15 just a month ago dropped support for 486 (from 1989)!
That's surprising. What is the 486 missing that Linux needs? Or is it that there are no volunteers to test and maintain Linux on a 486 (as often happens with older architectures)?
Open source software drops hardware support only when there are nobody left who volunteers to support that hardware. When does this happen? It happens when there are not enough users left of that hardware.
As long as there are enough users of some hardware, free software will support it, because the users of that hardware want it to.
