alt Hacker NewsIt mentions preemptive multitasking as one of its features. Are there any operating systems that still use cooperative multitasking?

I think it's worth mentioning on a hobby OS, just because it's a decent bit more work to do preemptive multitasking. It's a badge of honor to have successfully implemented it.
There is Wirth and Gutknecht's Oberon System. It's still available but is older than Visopsys -- it was created around 1990, then updated in 2013. I think it's now considered an historical artifact.
Many RTOS support it, eg FreeRTOS’s co-routines: https://www.freertos.org/Documentation/02-Kernel/02-Kernel-f...
