But that’s not how it works now, does it? There’s plenty of FOSS alternatives. postfix, mailcow, dovecot, openSMTPD, just to name a few. I’m sure the US government used or still uses postfix under the hood in certain circles btw, even if most of their IT provisioning just deals with Exchange.
This was my experience with it too. Until I realized that the issue everything boils down to is having an old gfx. In particular an old nvidia gfx that has old, closed source driver compatibility only and can’t initialize vulkan. I’ve still stuck to it, it’s arch running on my desktop, because I’ll upgrade hw components eventually. 12 years with a gtx 670 has been quite enough.
I’ve installed fedora workstation 41 on a decommissioned work laptop last week, a 2021 model with an 5700U, and everything just works out of the box. Some obscure game that I’ve been trying to play on my desktop, not even platinum rated on protondb, launched on first attempt without any shenanigans using heroic launcher.
Nvidia, especially older models, are probably just simply not the way to go for gaming on linux.
