What makes you think so? As it often happens, it is just a vocal minority that makes it look like something which it is simply not. Most people who are holding some bitcoins are definitely pro-growth. Of course, there are a lot of other people who want Bitcoin to die but they don't have a satoshi, so why should we care? They cannot bring the price down by selling their stashes since there's none. The only thing they can do is to open their mouths and say something negative against Bitcoin.
