No, his mispronunciation did not demonstrate a lack of knowledge, per se. I once hired a Russian programmer who, like Gore, mispronounced various technical terms. Had I drawn the illogical conclusion that you drew above, he wouldn't have even been hired, yet he was sharper than many, many technical people in my company.
He was Russian, Gore's American, and claiming to know what the Internet is and what runs it. Imagine hiring for a network engineer (American!) and he keeps referring to a "TCP/PI Stick."
