Part of Mozilla’s Manifesto:

The Internet is a global public resource that must remain open and accessible.

Part of Microsoft’s “Ten Grand Is Buried Here” campaign (emphasis added):

If you’re the first to locate the buried ten grand, you keep it.

How will you know if you’ve found it? It’s a cleverly concealed webpage that only Internet Explorer 8 can view. When you find it, it’ll be obvious that the $10,000 is yours.

Microsoft is still dreaming of that world of the past where the Internet was controlled by one company and accessible only from one platform, owned by that same company. Sorry, Microsoft, but I’d rather be without your ten grands and have an open web.

(Thanks to Patrick for pointing this out.)
