Less than a decade ago you made sure your web sites ran well in Internet Explorer, a closed source browser that was allowed to stagnate. IE took the W3Cs standards as more like "guidelines" and not a specification.
- Today, every major web browser (except IE) uses an open source rendering engine (or the browser itself is open source.
- Every major web framework and library is open source.
- Most of the servers running the web are powered by an open source OS.
- The standards bodies are actually working faster than ever on new version of Ecmascript and HTML.
- IE's marketshare is smaller than ever.
Years ago some guys had a crazy idea to make a browser for KDE. Today it's powering much of the desktop web and almost ALL of the mobile web. Perhaps I just like a good love story, but it seems like this is a pretty great achievement for "open". Now, it seems pretty disingenuous to say "the web is not open" and even more so to say that just because more people are working on the same open source project that it's, "becoming increasingly less [open]."
