Why do people on a technical website suggest this? It's literally the same snake oil as Cloudflare. Both have an endgame of total web DRM; they want to make sure users "aren't bots". Each time the DRM is cracked, they will increase its complexity of the "verifier". You will be running arbitrary code in your big 4 browser to ensure you're running a certified big 4 browser, with 10 trillion man hours of development, on an certified OS.

Because there is a real problem that needs to be solved one way or another.
