Public key crypto, properly implemented, does prevent MITM attacks.

It does, but modern public key crypto doesn’t encrypt any client data (RSA key exchange was the only one to my knowledge). It also only verifies the certificates, and the topic was about payload data (i.e. the site you want to view), which asymmetric crypto doesn’t deal with for performance reasons.

My post was not about “does TLS prevent undetected data manipulation” (it does), but rather if it’s the encryption that is responsible for it (it’s not unless you put AES-GCM into that umbrella term).
