Wrong. Signature campaigns have allowed making BTC for the average person a reality, they help distributing BTC around. Thanks to them, I have managed to make a decent "stack". It's not much, but it's something. Of course it's just a small extra and my main way to get BTC is by buying them, but think about poor people all over the world who can't afford buying anything. I know some people on the Philippines making above minimum wage thanks to signature campaigns. Let's not demonize one of the best use cases of Bitcoin. Everyone that gets some BTC off a signature campaings gets hooked forever. The average person is not going to give a fuck about Bitcoin if they have to buy it, but if they start making some small extra money on the side, they will start seeing the point and studying it further. Most people aren't going to be bothered to exchange fiat for BTC to try it out, so you can thank sig campaigns for helping on that side.
