Putting “here’s how we changed on a previous product” doesn’t really need to be on a small corporate site. It being a sort of investigation fits better on GitHub where fewer people will accidentally stumble across it from their current product.

There is a whole lot of bigging up their current product. That blog post is part of their marketing campaign. And the entire point of it is so people will get to their product.

Also:

* it's mixed up with all their other marketing material for this product.

* it's in their current product's repository

It's more likely people will stumble across it when looking at their product.

As I said in my edit. The reason for it being on their GitHub is to increase the likihood of GitHub stars which they use as social proof.
