The practice of calling anything other than Bitcoin a scam (or, less artfully, a s**tcoin) is sometimes labeled “toxic maximalism.” Online bitcoiners who defend the network against detractors and attack “imitators” are what MicroStrategy’s former CEO Michael Saylor called a “cybernetic immune system.” Historically, maximalism isn’t rare in tech – though it often results in embarrassment for any outspoken critics of, say, cars, planes, phones and the internet.
