I play games on a PS5 and some PC games. I personally don’t want to play on Stadia — buying games at full price with no guarantee they don’t cancel the service isn’t enticing to me. I did try it out, and the Stadia Pro offering wasn’t bad at all. It was just a limited selection.
But I’m curiously why you actually want them to sink.
I just don't want Google to have their fingers in so many pies. It's way too much power. I don't necessarily want game streaming as a concept to sink, although I have the same qualms as you do about ownership and so on. But the technology is interesting, as is the fact that it opens up avenues for gaming to people who would not have been able to earlier. But I don't want Google to succeed at it.
