Lol I knew I would get this kind of answer and downvotes.

You still have to make an account on a totally unrelated website. It's the shittiest experience one can think of.

But your excuse is "Hey actually you can also setup the whole application yourself before making the account to post a blog comment on an unrelated website, so that's actually super awesome!".

Absolutely ridiculous, and if any company you didn't like were to do something similar you would screech.
