I wonder if this is a useful tactic in making users of your platform continue to feel especially comfortable with it, by making other platforms feel particularly uncomfortable.
Firefox OS doesn't even really exist yet. Obviously, they need to bring new people in, and want people to be comfortable.
I work on web stuff and get requests like that all the time.
On the other hand, this classic xkcd is occasionally accurate. You get a few of these obnoxious ones from time to time: http://xkcd.com/793/
Also type designers keep making new fonts with tiny differences from older fonts because the older fonts were already used a lot and don't look fresh.
Just like programmers make new frameworks/libraries and using those is the cool thing to do.
Well, if the license permits it they can.
Another font that isn’t used anymore, but which was custom designed for a WebOS, is Font Bureau’s Prelude. I like that one a lot better than the choices all of the other platforms have made: http://palmwebos.org/wp-content/uploads/2009/07/webos-font-p...
