They put Eclipse vs Android Studio, but Eclipse is not a Google product.
At first glance I read that as "...but Eclipse is not a great product"
Android Studio is based on IntelliJ which is a far more polished IDE.
No this is Google simply replacing Eclipse with a superior product and was slowly transitioning people to it.
Did you really expect Google to drop Android development support for Eclipse overnight?
and youtube vs google video
This is mentioned at the end. However, Youtube was acquired and at the time Google Video already existed. Given the traction that Youtube already had, it's no wonder that they purchased Youtube regardless having their own video service.
