[MCU] Why did Sitwell mention Stephen Strange as a target of Project Insight?

Twofold question here.  
1) Why was Strange a target in the first place? At that point he was just a douchey neurosurgeon who didn't seem like he'd be much of a danger to anyone. Both his power and his moral turn only happened because of a specific series of events that couldn't be predicted.  
2) Why would Sitwell mention him by name? Strange was certainly famous *for a surgeon*, but there's no real reason for people to know his name. Even if Sitwell did because he was a significant target, it doesn't make sense to use it as an example. Was he somehow a household name? The only IRL neurosurgeon I could personally name is Ben Carson, and that's because of his political exploits, not surgical.

On point one, violent purges are nothing new, Insight just automated and compresses the process. Instead of ganking all the rival politicians and non-compliant military leaders in the first round, the philosophers and artists in round two, and the skilled trades/intelligentsia in round three, Insight murders them all *right now*. The algorithms determined that Strange, even without magic powers, was smart enough, flush enough and arrogant enough to serve as a nexus of political resistance if left alive, so it resolved to not leave him alive.

On point two, Strange managed to brand himself something of a rock star miracle worker by A) being that good and B) carefully picking his cases for maximum 'wow' factor and minimal chance of public error. He's managed to snag headlines with his antics, quite likely via self promotion; much like how people know Carson because he put his name out there, Strange also craved the applause and would seek out the spotlight, making him more than just some random neurosurgeon in the public eye.
