Not a programmer, but I can definitely attest that TV Medicine is wildly inaccurate. From CPR (method, success rate, reason for initiating) to the usefulness of various imaging modalities; it's like watching a gardener plant a whole watermelon and growing a sky-high beanstalk the following morning.
A really fun intersection of both of these was the episode of Bones I saw once when visiting my dad, where some corpse had a microscopic code etched in its femur that then hijacked/hacked the CT machine computer when scanned.
I think the larger point is that you can still block domains you don't want to see, but in this particular case defederation should happen. Both things can co-exist
