That was caldera that released their opendosĀ  as opensource, not Microsoft.

There were versions of ms dos that escaped into the wild, but it wasn't a sanctioned release from microsoft.

on them as a labor of love alongside a day job, and the potential,
as such projects become legacy software, for them to still be
half-maintained (and maybe maintain a significant user base) long
after an institutionally maintained project would have officially
been EOLed.

And there is something of that kind of risk with any DOS variety
still in use. Any remote execution vulnerability, through any
network-aware DOS software, is basically automatically a remote root
vulnerability by the nature of the system. Now, most FreeDOS users
are probably using it for retrogaming and such and not for anything
business-critical, but anybody using it in an embedded setting needs
to be really careful about exposing it to the network.

I really wonder how that would effect DOS, after all there is no
web interface, nor any Java in (Free)DOS. So (without having watched
this rather long video yet), any such conclusion seems to be a bit
far fetch IMHO...

The statement in the video (starts at about 24:00, for others who want
to watch it) was awkwardly made. This person makes the statement that
some open source projects should just shut down rather than keep going
(I'm paraphrasing broadly here). And gives the example of "If MS-DOS
were open source" he opines that it shouldn't go on.

Putting aside the fact that Microsoft did eventually release (early
versions of) MS-DOS under an open source license, this guy is just
wrong. Lots of people use DOS and FreeDOS to do useful things, like
running classic DOS games or applications, and supporting some
embedded systems or control systems.

I usually try to see the other person's point of view - but in this
case, he's off base. Whatever.
