This post is relatively meaningless; it's just some dude's vendetta against some other dude, so he blocks the guy's OpenID provider from using his blog. Whatever. The blog post is completely irrelevant because its all misshapen and skewed anyway, but thankfully that's not the important part.
The gold nugget, the priceless, sterling jewel of the post is in the comments section, where some commenters basically ask,
Isn't banning OpenID providers against the spirit of OpenID?
To which the author replies, verbatim,
How would the general users (i.e. non-geeks) know the particular provider/company is evil (which I believe is a good reason), unless they have problems using its services/products?
A moral authority for OpenID.
I mean, look, I can see blocking an OpenID provider for technical reasons like spam -- that day will eventually come -- but blocking one because you've got a beef, an arguably subjective beef at that, with the guy who runs the provider?
Man, come on, be serious. That is some serious high-school level drama there.
Even better, its not like people using the banned provider are going to be, "LULZ, MUST SWITCH PROVIDER."
Does he seriously, seriously think a "non-geek" is going to get another OpenID somewhere else, and now be using TWO OpenID providers? TWO? Now we're back to the whole problem of a different login for each site, because some motherfucker blocked another motherfucker, and started an iNuclearWinter.
At that point the value of having an OpenID (and actually USING it) quickly approaches 0, and we're back to jump again.
