Stadia was yet another platform that Google tried to make and failed. Yes, it was a rounding error in their budget, but that is largely the point!

They have become a financing company that is looking for where to spend money to make money. That they are spending a lot of money on developers will only last as long as that makes them money.

Again, this is not, necessarily, bad. I just don't trust them to make a software product that will survive outside of their garden.
