Stadia will completely avoid the issue of key resellers since I would imagine they are completely removed from the system of keys issued from publishers. They also have only announced plans to launch in US and Europe currently and it may never make economical sense to have an African datacenter for Stadia.
This telemetry thing is surprisingly overlooked in these discussions. I've disabled tracking and reporting on at least 4 separate occasions since windows auto updated my laptop from Windows 7 to windows 10 without user permission. They just keep adding auto-enabled features that override the previously disabled features doing the same thing.
"We heard you when you said you didn't want cameras automatically monitoring you. So we added this new feature where you can disable cameras based on DAY OF THE WEEK and turned every day on for your convenience"
Microsoft knows it lost the online tracking game, so it's playing dumb and putting in privacy-invading features and overriding user selections yearly. Why rely on a browser when you control the OS?
The paranoid part of me thinks windows is giving away windows 10 for free because it's making money selling the user data and access to intelligence agencies.
I know apple has received some flak for updates slowing their computers, but windows is no better. My 4 year old laptop is basically unusable at this point because every action takes 10-15s.
To be fair, people said this about Tesla and SpaceX as well.
Given his track record, I'm inclined to believe he understands the problem space and how to solve it better than you or I.
Yes, the burden is on him to execute, but that will take him years. The argument that "I don't understand it therefore it's invalid" holds little meaning. Musk isn't a person who gets this deep into a project without a high likelihood of success, historically.
But it's light-years ahead of WordPress+Woocom.
Neither of these are well set to run a proper ecommerce without heavy customizations though.
