It would be cool for one of these folks (or anyone really) to show us why these things won't work. I see people I respect in that thread but I'm also very tired of hearing about how trivial these things are and not seeing someone spend, according to them, very little time to bypass these things.

Obviously, I'm not smart enough to do it or else I'd be doing it. However, I'm not going around making wild claims either. I think something like that would help rather than hinder OpenBSD.

People have done this in the past, at this point most people are just going to meme about it rather than respond. The response that they get is always “if it’s so easy why don’t you hack it?” which is quite frankly more effort than anyone wants to spend on an OS that doesn’t really harm anyone just sitting by itself layering all sorts of “mitigations” on itself. They’re basically completely divorced from what any real-world exploit these days looks like (blind ROP, really?) or how attackers work (“99% secure will stop them!!”) but somehow always really convoluted and optimized at stopping one very specific exploit flow rather than a general technique. The real solution for stopping ROP/JOP is going to be CFI, shadow stacks, etc. rather than trying to kludge something on hardware that doesn’t support it.

I hear you. I guess I'd just like to see more hacking and less of the memes. For me I think again that it would help more than hurt.

I'm an old man now and maybe I've gone a bit soft but I don't see much benefit in mocking and am more interested in helping even if that means wasting a bit of time.

While I don't say it is, this is also a classical tactic to discredit something that could be a problem. This strategy has been used with other projects. If you are worried that this has potential it will ruin your project/income you're going to shit-talk it.

Some years ago there was a leak of plans to do that very with Tor. Spreading FUD so less secure systems are used. Discrediting contributors, turning people against each other and so on.

Common theme. If someone has a way to break something, they'd at least gain publicity for it, if they have any positive interest they'll at least mention a source or provide any chance for rebuttal (the whole point of the scientific method), if neither happens be at least skeptical.
