So it's not maintained by the OS vendors - it's maintained by the kernel support team?

Which is mostly from the OS vendors. Who do you think makes the kernel?

Whoever Linus Torvalds thinks submits a good kernel patch. Which today is mostly the OS vendors.

Red Hat, Suse and IBM do the majority of the work with Intel as an "also mentioned."
-
By 2011 this had changed some, Novell/Suse had fallen to fourth and Intel picked up the pace. Microsoft was at 17th at that point.
-
Canonical is probably somewhere up there in the top ten. But over time it remains that Red Hat, Suse, IBM and Intel are the big four that make Linux happen. And overall corporate is 75% of the kernel while volunteer is 25%.
Big banks, governments and military are all big contributors as well.

While your statement doesn't imply that the MD versions are different, it does lead one who's not knowledgeable to a false conclusion that each Linux distro (at least the base distros) are maintaining their own version of MD. According to Travis, since it's backed into the kernel, that's hopefully not the case.
Basically what I was trying to determine, is MD pretty much the same across all distros of Linux?

Why would it lead someone to that? There is only one Linux kernel, where would different versions come from and where was that implied?

Linux is Linux, MD is just part of it. There is one Linux kernel, one MD. Where is the idea that there are different Linux or MD or other components coming from? Honest question, what makes the assumption that a singular thing would naturally vary, happen? I saw nothing that would have led someone to think that, so I'm lost.

By 2015, corporate is now 80% of the Linux kernel development. Here is the latest contributions list: The Top 10 organizations sponsoring Linux kernel development since the last report include Intel, Red Hat, Linaro, Samsung, IBM, SUSE, Texas Instruments, Vision Engraving Systems, Google and Renesas.

You said it's supported by the OS vendors - since so many other OS vendors don't work together, why would I assume they would be working together.
A better response originally from you which would have stopped this whole thread of conversation would have been to say - it's supported by many OS vendors through their cooperative work on the kernel, where MD is supported natively now. or some such statement. Instead we're 30 posts later and only now getting that specific knowledge from probing questions, where the probes are made out to appear like ludicrous considerations.

Because we are talking about a single thing that they work together on. Shared projects exist everywhere from childhood through university to the professional world. We are talking about the MD product, no matter how many people work on it or where they come from, that doesn't imply and should not lead someone to think that each person helping is then making their own product. We have a thousand contributors to MangoLassi, but no one assumes that there are one thousand different communities. What makes MD a special case?

Or just accept simple answers and not inject unimplied assumptions. Since I had no idea that such an assumption would be brought to the table, it is very difficult to head it off at the pass. Of course if I could guess what people will randomly assume and correct it before it is assumed, I could make things simple. But there was nothing implying that assumption, so I had no reason to think that I needed to explain it.

Because @Dashrender wasn't aware of how it worked. I can totally see how someone could be very confused if they are not familiar with the Linux ecosystem.

Because while Linux is Linux, one distro is not the same as the next. And as I finally grasp, distros of Linux in some cases might as well be as different as Windows vs Mac (OK that's probably a bit far, because they don't share the same kernel, but I'm going for an over top example).
If I don't know what's in the kernel - and why would I assume, as a non Linux guy, that MD is in the kernel, why would assume MD would be in every distro of Linux?
Just like normal, those that don't know Linux at all are often made to feel like idiots because we don't know/understand what goes where, what's including in every Linux distro, what's not, why one shell is here and a different one is there, etc.

Think about the AirBus 320. It was designed and made by one German and one French company (primarily.) Yet no one assumes that the two companies made two different products that only shared the name "AirBus". That the project was a collaboration and that the result was a single product (we only mentioned the one) there is every implication that there is just one thing being discussed and no reason to think that the collaboration was actually to make competing products.

Even if you don't know it is Linux and assume it is something totally different, there is just the one product being discussed, though. Even if this was closed source and made by Microsoft and Oracle we'd still assume collaboration since only one product was the result.

Sure, see - now you're making an assumption that MD is understood by the masses (I'll even limit that to the IT masses) that it's a thing like the kernel - that there is only one. Why should I assume there is only one MD where there are dozens of shells? To me that is fraking crazy - one shell to rule them all, please and thank you!

You wouldn't assume that it is in the kernel, but that's not important. That it is part of Linux or its own project, doesn't matter. It's one thing. There are tons of things on Linux distros (and on all software) that are third party. MD might be in some distros and not others, but when it exists, it is MD, not some random thing called MD.
Does that make sense? We are talking about one thing, not a generic name.
Think about the glances command. Some distros have it, some do not. But there is only one glances and it is not made by Linux in any way.
