The insane thing is that, because the VPN has a 1GB/month traffic limit, there is no way to enforce it unless they associate all traffic with a Microsoft controlled user identity. Cloudflare literally has to keep track of any sites you visit and associate them to your ID to make it work.

Though, I do believe that for connections from public WiFi it's somewhat of an improvement. It establishes a minimal security baseline of: "ok, we'll sell your data and let FBI snoop on you, but we won't inject trojans in your downloads and then hijack your webcam to create ransom-porn (though the FBI/??? might)".
