Let's look at it this way.
Say, for instance, it has been suggested a popular soft drink gave you cancer. The company who make the drink have investigated this, found it to be true, but are spending millions covering up, denying and rubbishing the suggestions. We're talking a massive scale lie and fraud here. They are being so successful at doing this that you are convinced, and are happily continuing to consume the drink. You've got a can of it by your computer right now.
A few years from now you're going to discover you've been lied to, and it's almost certainly going to kill you.
Still think you'll have nothing to complain about? Did they force you to buy that can? Are they putting it to your lips? Nope, it's all your decision. The fact that you are being tricked doesn't matter. Man up, sucker.
