ReactOS underwent a big audit years ago because people kept saying things like this, and AFAIK it's over and nothing exciting turned up.

The author of post, Axel Rietschin at Microsoft, should remove this post and publicly apologize for his baseless defamation of ReactOS ("like a baby mosquito on the back of an giant elephant") if he cannot give authoritative evidence to back his claims. There may be copyright issues in some subroutines, but calling the entire project "a ripoff of the Windows Research Kernel" is an extraordinary, arrogant claim. If you have extraordinary evidence, fair enough, otherwise you should STFU.
Update: my original comment was refering to the author's original answer, which didn't give a single symbol name. But apparently, the author registered an HN comment and start giving more details than what has been said in the original answer, I need to stick to the facts so I'd say the credibility of the accusation is no longer 100% "baseless". Let's see what is going to be the evidence.
It’s my personal opinion and it’s based on my lecture of ReactOS code at the time I downloaded it (circa when I wrote my reply on Quora). I think anyone who can read C code can reach similar conclusions just by eyeballing the code in ReactOS and the code from the leaked Research Kernel, that can be found for example on GitHub. As a matter fact, someone on this thread did just that and it did not take that person very long (just minutes) to find some of the similarities that I, for one, qualify as troubling. It should not be a problem for anyone to repeat the experiment, all code is available for download. So why not go ahead and see that code with your own eyes? I think it’s highly improbable that a reimplementation of that magnitude came so close from the original in so many respects. I’ve been conducting interviews for years and screened some of the best and most promising future engineers coming from the best universities and I always ask the same coding questions. I was given many decent and correct answers, but never the actual implementation was similar to the level I can observe between ReactOS and the leaked Microsoft code. In fact every candidate wrote very different answers to the very same question, some even had very different approaches to the resolution of the same problems. I cannot explain how a team of people on a hyper-complex open source project can write nearly the same code - the source code looks very similar down to peculiar formatting idiosyncrasies - as a separate team of developers of the original closed-source project, just from observing the external behavior and/or reading the documentation, if available at all. I think this is impossible.

It would be interesting to see if this statement comes back to bite you in court if the opposite accusation is ever made. That Windows kernel developers have been stealing from GPL code :)

I presume you quit working on Windows after you read the ReactOS source code, offered to you under the GPL license only? Or is Microsoft planning to release it under a compatible license?

Your interview analogy is a bad one. Because they are not trying to make their solutions as similar as possible to each other.
If you had interviewee A write some piece of code, and then said to interviewee B "I want you to solve this problem as close as possible as the person before you did it, here is their executable", you'd be quite surprised what they could do. Especially if interviewee B is Alex Ionescu.
I don't suppose you ever compared parts of the tree that weren't present in the various sort-of-public NT source leaks or research kernel, to see if idiosyncrasies there matched as well?
> It’s my personal opinion
Others in the thread have pointed out several verifiably false fact claims in it, so it's both derogatory and at least in part factually false, not a mere matter of subjective opinion.
Saying "like a baby mosquito on the back of an giant elephant" is not a defamation. It's a metaphor. He's saying that the project doesn't really threaten Microsoft so they'll probably just ignore it.
>baseless defamation of ReactOS ("like a baby mosquito on the back of an giant elephant")
If only he had called it a cancer. That seems to work well generally.
The infamous "cancer" analogy was referring to the copyleft-licensing, not the actual system per se.
Saying ReactOS infringes 200+ Microsoft patents and threatening for lawsuits to developers and all users is a more effective FUD approach to me, and may even be factually true. The entire project of Linux kernel was running under this threat for 10+ years until ~2005 (?) when an agreement was established.

Don't we all think if the accusations were true, Microsoft would have aggressively persued legal action? Remember that guy they sued into oblivion and maybe prison over "rescue discs" for old PCs? Microsoft it notoriously sue happy. Why not here?
Because reactos is irrelevant to Microsoft?
The project has been around for 20 years, it's not likely to cause MSFT to lose any revenue any time soon, and there is no large corporation to extract money from in a lawsuit.
It's basically the same reason they don't go after people who have a pirated version of Windows and just show them a "this is fake" warning.
Also, attempting to take it down would surely cause reputation damage to Microsoft. The "old" Microsoft is somewhat infamous. Going after the small guy would not help their image.
I hate to say this: the guy who printed the "rescue disks" also decided to put the standard Windows Install Disk graphics on them. He got sued over the whole thing, but they look the same, and he didn't pay is what got him.
Because Nadella is trying hard to win the hearts of developers and attacking an open source project now like they did with Linux would backfire on them.
Because what Microsoft did instead was offer Alex Ionescu a job.
