I won't try to defend Chomsky. (Not really a big fan even before this.) But if the mere mention of him is sus to you then I advise you to not study either linguistics or computer science because it's Chomsky normal forms and Chomsky hierarchies all the way down. There's even still people clinging to some iteration of the universal grammar despite the beating it has taken lately.

He's also one of the most prominent political thinkers on the American hard left for the last half century.

There's a joke going around for a while now that you either know Chomsky for his politics, or for his work in linguistics and discrete mathematics, and you are shocked to discover his other work. I guess we can extend that to a third category of fame, or infamy.
