Well, of course this is not a harmless protest, all users of that site suffer from this, and it does big time damage to that company.<p>I can't see in what way it has been 'hacked' (defaced?) though.<p>It doesn't matter what you change to a website, there will <i>always</i> be a portion of the users that dislikes it.<p>Some people simply don't like change some people simply like to be jerks and will use any excuse.<p>The site belongs to the owners to do with as they please, it is not exactly a community. Communities are different in the sense that I believe they belong to the participants, not to whoever built it.<p>They get to reap the benefits, but you mess with communities at your peril if you do not involve the users in the decision making process.
