Whenever a story like this happens, I'm left wondering who came up with those ideas and who okayed them. From my perspective, anyone who thinks those things (as they were implemented) were justified is not suited to make decisions in a project like Firefox, period.

Another comment in this thread asked what will be done to make sure something like this doesn't ever happen again. I am aware that probably, nobody here can answer that question. But in essence, this is the thing Mozilla should be considering and communicating clearly in the near future.
