For those, who got an SSL error: You're right.
Redirect didn`t work.
That's why you got an error when you didn't use https as said in the original link.
You could in actual MS/PC/DR-DOS. It was Windows NT that introduced this prohibition, that was also in OS/2 before it. Also, CD A: did not change the current drive letter.
Yeah you’re right it would just be A: to switch the drive… it’s been many many years… but I am sure that you couldn’t format the disk from within it on MS-DOS 5.0 and 6.22 (except maybe with some undocumented switch) because I remember struggling with that problem back in the hiatus summer of ‘92 when I revamping my very mediocre 386SX-16 for the newfangled Windows 3.1.
The rules were different when add-ons like SMARTDRV or Super PC-Kwik were installed, and in a VDM inside 386 Enhanced Mode DOS+Windows. But vanilla MS/PC/DR-DOS originally just calmly let one format the disc out from underneath onesself.
It’s an app, not a system-integrated[1] screensaver?

Except dos isn't the PC experience. It was back in the 90s when you'd edit your config.sys and autoexec.bat to shift your himem settings so you could run a given game with your soundblaster
That world doesn't exist any more, whether you're on a mac, linux, or any other OS.
Way back I hacked together a VB6 application (don't remember what it did) but after a while it popped up a new window that faked a DOS prompt formatting the c drive. Then I send it to my best bud on April 1st with a message "Hey, check out this new program I made!" :-)
Things not on my bingo card: Watching Hacker News denizens download, install, and run vibecoded Mac apps from sketchy vibecoded websites with TLS issues.
There was some memory command you could stick in someone's autoexec.bat that made the machine reboot so it got stuck in an infinite reboot loop until you stopped it using f5 or f8.
I remember the days when `format` with no arguments would happily format drive C: out from under you. I worked in a computer lab at my college where it happened more than once before we put `format.bat` files on all the PCs.
something like this was among the first programs i wrote when i was a kid; back then - in turbo pascal - for pranking my (~10 year old) cousin. the program created a fake dos that printed warning messages about finding a virus, attempting to delete said virus and failing, then - as a last measure - fake-formatting C and exiting. i then set the "dir" defaults to show only files with a name that didn't exist, so when he typed "dir", an empty harddisk was shown.
the trick was to name the exe non-breaking-space - alt+255 - which was a valid filename and then adding it to the end of the autoexec.bat.

Yeah, that’s wrong.

I feel like the author is... missing a point here...

Kinda worse. Some Mac application that acts as a screensaver and shows a DOS-prompt when idle...
Either way, I like the idea of getting people to install and configure fun apps which then know exactly when a PC is not in use.
Could be a useful swarm of devices...
Instead it's a somewhat sketchy app that by design happens to know exactly when my PC is not in use...

ps: my cousin started to cry.
