When Intel designed the 286/386, they created 4 hierarchical privilege rings:
• Ring 0: Core Kernel
• Ring 1: Device Drivers
• Ring 2: OS Services & Subsystems
• Ring 3: User Applications
The idea? Fine-grained hardware security.
So why do modern OS's only use 0 & 3?

State level business deals ≠ crony capitalism at the Centre.
Whataboutism + BSDK wont make your argument strong
Google killed Flutter
Google killed Android Java
Google killed Firebase Studio
Google is going to kill Gemini
Google always starts its own products, only to kill them later.
