This behavior isn't just annoying to others; it's harmful to his own goals. If Maciej had hedged his bets and accepted Bitcoin payments for Pinboard in 2013[1], it would most have been the most cost-effective action of his entire life. He would be worth millions more today. He could have used that money to further causes he cares about, such as climate change and social issues.
Instead, he's trying to ban cryptocurrency. We had this same debate with cryptography in the 1990s and DRM removal software in the 2000s. Back then, technically-inclined people agreed that you can't ban math. But now many are trying to do just that. What exactly would a cryptocurrency ban look like? Would calculating lots of SHA-256 hashes cause men with guns to come to your home and put you in a cage? It sounds more absurd than what happened to DVD Jon.[2]
