Thinking for two seconds:
MS pays Google to start enforcing some device verification thing so you can only view a good chunk of the Internet if you pass verification? (Assumes Google goes even harder making the web Chrome-focused)
Ooh Cloudflare could be invited to the party here too. Constant CAPTCHAs if you’re not on an MS AUTHENTI-PC! device. (Think Private Access Token)
…fill in the gaps friends 😉 you know MS has already debated all your “suggestions” anyway
