If you bothered to look at their download site, you'd see they support Mac in addition to Windows.

That's a pretty high horse you're on there.

This has nothing to do with closed source vs. FOSS. The examples I was referring to are small, non-critical applications where nobody needs to get fired because a cert warning appeared in someone's browser.

I usually figure out that a cert has expired when something breaks. For example, I like to use free certs from StartSSL on Exchange Servers. When they expire, people get warnings when accessing OWA, or smartphones stop connecting.

If it happens to be on an SBS Server it can really be a pain, however, since it will stop working as a Terminal Services Gateway, making it difficult to log back on and replace the cert.

Wow. You sound inordinately passionate about April 1st. If such articles are so much to your liking, perhaps it's you who needs to go elsewhere. May I suggest America's Finest News Source?

As for this site, the motto used to be "stuff that matters". When April Fools articles become so numerous, it's no longer amusing. It's like the same joke being told over and over again. April Fools is not a "huge holiday". It's a day literally intended for fools, and only a fool finds the same joke funny time after time.

Your example misses the point:

OK, this is clearly a bad thing, but I don't think it means that your private LAN is immediately accessible to people all over the world does it? Multiple routers using the same keys means you could be tricked into logging in to someone else's router without knowing, but that would still require some way of directing your traffic to the imposter's device to begin with, such as DNS hijacking.

Knowing someone's keys would also allow you to encrypt/decrypt traffic as that device, facilitating a man-in-the-middle attack, but still, you need a way to get in the middle between two devices. This is not something that's trivial to do from one arbitrary location to another.

I'm not suggesting this isn't a serious problem, but I don't think it's as bad as, say, remote administration being enabled with a known default password.

What's wrong with asking that? Both Excel and Acrobat have built-in encryption capabilities. There's nothing ignorant about considering whether the built-in functionality is sufficient.

Once again, Godwin's Law is proven.

Seriously though, you're making the wrong comparison. From descriptions I've read, the ISIS video contains quite a lengthy rant before the murder takes place. A more apropos question would be whether the Allies should have aired Hitler's speeches to the masses during the war.
