The PC gaming community alone would kill this plan. Data caps make game steaming for long periods untenable and Valve has explicitly been focusing on Linux and Proton for the last decade to try and prepare for Microsoft doing something like this. Apple just released their game conversion toolkit or whatever that shows promise for (relatively) quick and easy ports of Windows games to M2 Macs. Having a streaming connection to play games would be laughable to anyone in the eSports community and would immediately result in companies abandoning Windows.
Literally why
They already have Truth Social and Twitter.
