That is no lie, but it is the ugly truth of bitcoin, that most people involved with bitcoin aren't here because they are idealistic, moral and ethical. They are here because they are promised an easy way to get rich. The talks of freedom and liberty are just marketing techniques to sell bitcoins to those who know less.
Bitcoin kind of reminds me the communism movement. On the outside, it looked like idealistic people want to give more freedom and liberty to the people, but really they were just interested in redistributing power to their favor, while actually concentrating power even more then before.
That's just your cynical point of view, not the 'ugly truth'. You're just making assumptions as to what most people are in it for and that's your entire argument against it? I think for many it's a combination of things. Some see Bitcoin as a better form of money because there is no central authority having a monopoly on its creation and there is no limitless supply that can be created out of nowhere. It also cuts out middlemen like banks which is also a very positive thing for many. Others just see it as a practical tool to move money around and across borders almost for free. Anyway there are many reasons why people would like to get into Bitcoin, not just to make a lot of money. But even if it's only about becoming rich for some, how is that different from the people who invested early in Apple or Google? Are those companies bad because of greedy speculators/early adopters as well? There is a lot of risk involved with it too, so it's not an easy way to get rich at all because there is absolutely no guarantee that Bitcoin will succeed. I may lose it all if it fails. So in short I think your argument is flawed and biased but hey, you're entitled to your own opinion.
