I run Mac OS.

I am aware that it builds on BSD.

Yet BSD is very alive and nobody who wants BSD is lost to Mac.

At least I personally have never heard anyone deliberating over a free BSD vs Mac.

Edit: and of course upvote. Apple ran with it. But they didn't run away with it. We still have it. Actually we have some patches thanks to them. As I mentioned in my other reply: Open source is not a zero sum game.

Well, macOS is sort of BSD, but not quite. The kernel isn’t really BSD despite large sections being originally taken from BSD. The XNU kernel isn’t really BSD anymore. Then, the userland (BSD is both kernel and userland developed together) isn’t really BSD anymore, and Apple neglects their UNIX userland anyhow.

Don’t forget the PS5! At it’s heart it’s just a computer running FreeBSD.

Which one? They have dozens of “OSes” across their various products.

Cisco IOS is absolutely not based on BSD - it is a proprietary kernel, and such that it even has a “userland”, a proprietary userland.

IOS XE is based on Linux.

Most of the voice stuff is Linux.

Perhaps you are thinking of Juniper’s JunOS, which is based on FreeBSD?

I don't know. But if so, what?

Have you caught anyone deciding to go with Cisco instead of BSDs on their servers or their laptop?

I'm serious here: Open source isn't a zero sum game.

Partially thanks to the permissive license of BSD we now have both Mac OS and JunOS (edited: it said Cisco first), which is a good thing, not a bad thing.

The problem with Chrome isn't that it exist but that it has been forced upon us and the fact that we know they have used questionable methods to establish it as the dominant browser.
