101 posts and not a single one with technical content. Somebody should create a slashdot post generator, with modules producing output of these kinds:
- internet meme repeater ("year of Linux on the desktop", "stallman eats his own toes", "thou shalt not compare to nazi");
- xkcd repeater (its output is prefixed by the string "obligatory" and displays a strong prevalence of this one);
- project deprecator ("this software is so stupid, I could write a better one with one arm tied behind my back, except I'm too smart to actually do it");
- Google/Apple/Microsoft PR ("it's not Google who kills kittens! It's their subcontractors!");
and, last but not least,
- Slashdot deprecator ("slashdot is no longer a nice site to read these days").

No. They don't want to protect the binary blobs from your eyes. They're not encrypting, they're signing. They want to prevent you from developing your own blob, by having your video card reject firmware not written by them.

It's not a matter of opinion. They are anti-open source by definition, it's a fact dictated by their actions. They're locking down the cards that they manufacture in order to prevent their owners from writing open-source software to drive them. You can't get more anti-open source than this. Nvidia have always been anti-open source, and they are getting worse and worse with time.

1) Whatever it does, it can be nullified by malware that gains root-level access AFTER the OS has booted (which is the norm). And if the malware managed to modify the bootloader, of course it has already gained that access, hence no effective protection is added, UNLESS you are running a machine that doesn't allow unsigned software to run (EXEs, batch scripts, stuff written by the user) that could have been installed or patched by the malware. But clearly this is not Windows as we know it today.
Moreover, locking down the machine (this is the only firmware behaviour authorized by Microsoft when the so-called Secure Boot restriction is violated) is arguably the worst outcome for desktop users, as they will be left with no way to service the machine (beyond running "rescue partitions" which of course are static and therefore can't contain anti-malware software), and with no access to their data.
2) Malware that operates by modifying the boot sequence is extremely rare today, because it must target specific hardware, and is associated with government-sponsored attacks. Of course, three-letter agencies are only a piece of paper away from having their malware signed with legitimate keys.

Read the thread. I'm no parrot.

"Unless" is they key word here.

Imagine that I am an operating system vendor and I want to sell an OS. Describe exactly what I have to tell my customers before I sell them my OS.

Imagine that I know an unskilled person (grandma) running an old version of Windows that is no longer supported on an otherwise perfectly fine machine. Describe exactly what I have to tell her before I propose to install Linux, or a commercial OS costing less than the new version of Windows, on her PC.

Imagine that I am a student and I've heard about this Linux thing. I'd like to try it on my PC that I bought off a shelf a couple years ago. Describe exactly what I should do to try Linux on my machine, fix it when it doesn't work and add new features to its kernel.

I don't know if you're the same Microsoft supporter as before, but in case you aren't, I'll repeat that we are talking about "designed for Windows 10" machines which aren't for sale yet.

No, because that would prevent the user from buying copies of future versions of Microsoft Windows.

Because the OEMs are known not to care about letting the users fiddle with advanced boot options. They are also known to make firmware that, for example, will crash the machine from SMM when running a non-Windows OS: I've owned such PCs (that bug was meant to be a fix to make Windows 2000 run on that hardware). If the machines they make don't boot Linux, it's because they don't care, or haven't the resources to support Linux, not because of malice. But it's Microsoft who put these hurdles for them (and the users) to overcome. It's their decision that will lock people out of their own PCs, not the disinterest of the OEMs, which has always been there and is not changing.

Yes of course. That's where I usually lose most of my karma points.

You've just admitted that there's "overhead" in the overall process of the OEM to add an option that disables the so-called Secure Boot. Hence, OEMs that want to get rid of this "overhead" WILL remove the option. Thanks for proving my point.

That is, to keep Linux out of of the users' PC as I've been stating from the beginning!

My friend, in this world pressures against OEMs are the norm, not an exception.

I'm not denying that Linux users are a minority. I'm stating that they risk to become zero thanks to these dirty tricks. And this will harm the market of Linux on the servers, too, because of the way how people become Linux contributors. And I'm stating this in a comment which, if you bother to read, was meant as a response to someone who said "Microsoft supports Linux now".

They have been doing stuff like this endlessly for decades. Remember Bill Gates' "we should make ACPI Windows-only" in the 90s?

A statement is true when it's always true, not when it's true sometimes and sometimes not. You didn't even bother following the line of reasoning.
Microsoft supporter: "SecureBoot is useful and gives no problem to the user"
Me: "No, it's unuseful and here's how it harms the user"
Microsoft supporter: "Eh, but you can always turn it off"
Me: "Not anymore."
