The following is presented as indisputable facts in the article:

Bitcoin is a scam

Bitcoin is a Ponzi scheme

There is zero chance that bitcoin will ever be mainstream

Bitcoin does not have a single advantage over fiat currency

Bitcoin will never be useful for online shopping

None of the problems with bitcoin can be fixed

All bitcoin users and developers are incompetent, does not know anything about economics, does not understand people at all and has no understanding on how to build reliable financial computing infrastructure

Looks pretty one-sided to me.
