Because apparently we're not allowed to find the browser UI changes to be anything less than objectively stellar improvements. (Think I'm exaggerating? Just try raising any objections to any browser UI changes to them or even suggesting that they be optional, and just see how people react.)
Because that's just how people are. Take a look at the Thread that spawned from the std.process vote.
One person tried to start a conversation about allocations in Phobos, and maybe it would be good to avoid them whenever possible.
And bless his heart he eventually succeeded. Eventually. After cursing a few times because people were obviously not reading (or thinking!) about his responses.
Another example? Gnome 3. Nothing more needs to be said about that.
