I’ve done the horrible deed of updating Debian, for example.
Distros like Arch get a pass, but Debian screwed me over several times. For example a few years ago, some driver decided to make itself clinge onto old kernel versions. So the boot partition got full and left me in a weird start where I had to manually remove old kernels and track down the driver at fault.
Recoverable, but annoying, and on a system I use for work it would be really really expensive.
Fedora used to nuke itself sometimes if you upgraded an install from version n to n+1, n+2, … Like a config not being migrated properly, a package conflict because of renamed packages and versions, yada yada yada.
If you didn’t experience that, you either were very lucky, only used enterprise distros, or simply reinstalled often enough for it not to be an issue.
But they made half a million.
And there are literally hundreds of similar companies raking in billions in investments that magically vanish while the founders live a luxury live and move on.
The real question is: why do VCs shit so much money into obvious frauds? Are they this stupid or do they just hope to pass it on to the greater fool?
