If they're so concerned about protecting their mission, I don't see why they encourage use of Kodi (well I do understand it, it sells boards, but Android support could be a good selling point too).
Edit: by blindly clicking around I found a post from a Foundation member that said they were locking the forum. Dated mid-March 2015, so i guess the css wouldn't matter anyway
As I said, I have proof via a PM from a forum mod that the CSS on that subforum was intentionally broken (it'd be easy to fix). The aim was to discourage any discussion of Android on the Raspberry Pi, as they saw it as going against the aims of the Raspberry Pi Foundation (the suggestion being that if students had access to Android they'd mostly use it with Android). There were three parts to blocking those discussions. First was to lock the Android subforum. Second was to mess up the CSS on that subforum so it was harder to use as an archive. Third was to lock/remove threads across all forums (including General Discussion) that were about Android on RPi.
If you don't believe me, try posting a thread on the Raspberry Pi General Discussion subforum about some recent Android on the Raspberry Pi progress:

If it is really about education, get small inexpensive devices in the hands of millions, children... does things should be welcomed. Hell some of them attack a guy that wants to experiment with a different open source OS, that seems extremely conflicting with an open platform from my POV.
For me it is the opposite of being "open", seems more a marketing ploy to me.
