It's not mean, it's just very skewed in one way without acknowledging different perspectives. Take this sentence:
> At best your typical crypto project is just a planet-destroying unregulated casino, at worst it's criminal fraud
Obviously the "at best" part is still a negative, just like the "at worst". That's no way of starting a curious conversation and frankly, it makes for boring reading no matter if you're for/against cryptocurrencies as a whole.
