It does matter, it is important. Making such a mistake calls into question if they don't have other, more serious, mistakes in their actual articles.

I don't make extraordinary claims so I am not bound to provide any extraordinary evidence. They do make an extraordinary claim.

That seems like a pretty extraordinary claim to me. That you've made. Twice.
This shows such black-and-white thinking, thinking in absolutes that doesn't take in account, the context and circumstances.
To me it shows a rigid mind that can't perceive nuance, and think / reason about topics in a particular context.
Minor mistakes are often just that: minor mistakes. If this was an error in a scientific paper or news article, your stance may have had more merit. But that's not the context here at all.
> I don't make extraordinary claims so I am not bound to provide any extraordinary evidence. They do make an extraordinary claim.
A blog claiming not to track you isn't an 'extraordinary claim' by any definition. So that's a mistake on your part, so I can't take anything you say seriously anymore, by your own definition.
And you seem to read way too much into this mistake, promptly distrusting all the content they ever made or wrote.
Next time you make a mistake, I hope people around you will treat you the same way you treat other people, let’s find out if you like that.
