A lot of that sort of armor is more designed to deflect hits off of it. If someone can get a solid hit in, it's possible to cut through it.
Which leads to another pet peeve of mine, which is armor that's clearly designed in a way that it wouldn't be good at deflecting hits. Particularly anything for women that has cups for the breasts.
DDG has also really gone downhill for me. It's still noticeably better than Google, but DDG nows does a lot of the same shit that originally made me give up on Google years ago. I'm assuming a big part of this is because DDG heavily sources their results from Bing, and while Bing does manage to be better than Google, it's not much better.
I really need to put some effort into trying out a few more search engines and seeing if they are any better. Last time I looked, many of them were also pulling results from Bing so they all had similar issues.
