Google has this culture that you need to make something to be something, usually someone will have an idea to make a product, then the product is quite successful and they get promoted away from managing that product.

Then someone gets assigned to manage that product, since that someone new also wants to make “something” to be something, they put their own spin on that product.

Since they’re not the one who made the product in the first place, they missed what made the product great.

This causes the product to lose quality, and therefore the user base. With a reduced user base, there’s no justification to keep the product alive, so Google pulled the plug on the product.

It’s a vicious cycle that results in a lot of things made and killed by Google.
